Modifier

Note: Please see the talk page for suggested changes for this page.

Modifiers are found on a variety of Uncommon, Rare, Very Rare, Ultra Rare, and Epic items, such as weapons, armor, engines, deflectors, and shields. The greater the rarity, the more modifiers (uncommon 1 mod, rare 2 mods, very rare 3 mods, ultra rare 4 mods and epic 5 mods). The same modifiers may appear multiple times (e.g. [Acc]x2, [Cap]x3, etc.).

Existing modifiers on items can be re-rolled through re-engineering.

The modifiers that exist on each type of item are given below:

Ship Beams	[CrtD]	[CrtH]	[Acc]	[Dmg]	[Snare]	[Thrust]	[Pen]	[Over]	[Arc]
Ship Cannons	[CrtD]	[CrtH]	[Acc]	[Dmg]	[Snare]	[Thrust]	[Pen]	[Rapid]	[CrtX]	[Arc]

Kit frame modifiers[]

Kit frames have additional modifiers that boost various skills. Both Common and Uncommon kits have one modifier; each quality improvement after that adds one modifier. The amount the skill granted by each modifier at a given Mk level is the same whether the kit is Uncommon, Rare, Very Rare, Ultra Rare, or Epic, though Common-quality kits have reduced stats.

[Dire] scaling is as follows:
- Bonus All Damage scales linearly at 5 + 0.15% Bonus All Damage per 1% of Health above one third of max health. Thus:
- From 0 to 33.33% Health, it gives +5% Bonus All Damage
- At 50% Health, it gives 5 + (0.15 * 16.66)% = 5 + 2.5% = 7.5% Bonus All Damage
- At 100% Health, it gives 5 + (0.15 * 66.66)% = 5 + 10% = +15% Bonus All Damage.

Deflector Dish modifiers[]

Deflector Dishes may have additional modifiers that boost various skills. The amount the skill is boosted at a given Mk level is equal to half the amount a deflector's innate skills get at that Mk level. It is possible for a Deflector to have the same modifier more than once. Below are examples of Deflector modifiers.

Uncommon deflectors will have one modifier, Rare will have two, and Very Rare will have three, Ultra Rare will have four. All Epic Deflectors have [Sh/HullCap] as their default fifth modifier, though this can be re-engineered into a different modifier. The [CtrlX] modifier seems to have the highest chance of appearing multiple times on a given deflector.

↑ The drain resistance part of the [DrainX] mod was known as [Ins] during a previous skill system—standing for Starship Power Insulators—until Power Insulators was rolled into it. For a time after, [Ins] still appeared but erroneously gave Control Expertise; any old items with this problem were converted to correctly give Drain Expertise instead. It still appears on some Deflectors, and [Ins] is now aliased to [DrainX] on the exchange to ensure those searching for the old mod can find the new one.
↑ The [ShdHeal] mod was known as [Em] during the old skill system—standing for Starship Shield Emitters—and for some time after. It still appears on some Deflectors, and [Em] is now aliased to [ShdHeal] on the exchange to ensure those searching for the old mod can find the new one.
↑ Sometimes these stats are integrated into other special deflectors, including Elite Fleet Deflectors themselves.
↑
[ColCrit] scaling is as follows:
- CrtH scales linearly at 0.04% Critical Chance per 1% of Hull HP, for a maximum +4% Critical Chance at 100% Hull HP.
- CrtD scales linearly at 5 + 0.15% Critical Severity per 1% of Hull HP above one third of max hull. Thus:
- From 0 to 33.33% Hull, it gives +5% Critical Severity
- At 50% Hull, it gives 5 + (0.15 * 16.66)% = 5 + 2.5% = 7.5% Critical Severity
- At 100% Hull, it gives 5 + (0.15 * 66.66)% = 5 + 10% = +15% Critical Severity.
↑ "It is no longer possible for crafted Deflectors ... to gain the [PvP Res] and [PvP Dmg] attachments. "
↑ "Resolved an issue that was allowing [PvP Res] and [PvP Dmg] mods to still appear on crafted Deflector Dishes."

The sum between X modifier value and the same basic deflector stat will be also rounded. For example, a [Neutrino Deflector Array Mk V [CtrlX]] will display +13 Starship Control Expertise instead of +13.2.

Secondary Deflector modifiers[]

Like standard Deflectors, Uncommon, Rare, Ultra Rare, and Epic Secondary Deflectors gain additional modifiers, however these items also gain a single special enhancement at Very Rare rarity. All Epic Secondary Deflectors have [EPG/ShdHeal] as their default fifth modifier, though this can be re-engineered into a different modifier. The amount the skill is boosted at a given Mk level seems to be about ¹⁴/₁₅, or halfway between what a primary deflector gets innately, and what it gets from a mod. It is possible for a Secondary Deflector to have the same modifier more than once, up to a max of 3 times (at Uncommon, Rare, and Ultra Rare). The following is a list of possible Secondary Deflector modifiers:

Standard
Modifier	Effect	Modifier	Effect
[CtrlX]	+X Starship Control Expertise	[DrainX]	+X Starship Drain Expertise
[ShdHeal]	+X Starship Shield Restoration	[EPG]	+X Starship Exotic Particle Generator
[HullCap]	+X Starship Hull Capacity	[ShCap]	+X Starship Shield Capacity
Very Rare
[SA -Def]	Sensor Analysis (-Defense): The enemy target of your Sensor Analysis ability will also receive a Defense debuff that increases in effectiveness the longer you have the target under the effect of that ability. The debuff is -2% per stack, up to a maximum of -12% at six stacks.
[SA +Heal]	Sensor Analysis (+Heal): Improves the healing buff of Sensor Analysis when used on a friendly target by 20%.
[SA +Dmg]	Sensor Analysis (+Damage): Improves the damage buff of Sensor Analysis when used on an enemy target by 20%.
[+Chance]	Precision Sub-System Targeting: Improves the chance for Subsystem Targeting abilities to knock a subsystem offline by 25%.

Impulse engine modifiers[]

Some Impulse Engines may have additional modifiers that either increase existing bonuses or add new ones. Uncommon engines will have one modifier, Rare will have two, Very Rare three, and Ultra Rare four. All Epic Engines have [SecSpd-2] as their default fifth modifier, though this can be re-engineered into a different modifier. Below are examples of Impulse Engine modifiers. Some Engines and modifiers boost Skills by a certain amount, based on Mark level. Refer to the table above for these values.

[Aux]	Thrusters: 25% speed when engines are disabled.
[Spd]	+10% Flight Speed.^{[mods 1]}

↑ Can appear twice on one engine, though Fleet Engines and some special engines have 3 or more innate or added [Spd] mods, and engines can be re-engineered to have more. After calculating the base speed for the Engine's Mark level, the game will add 10% for one [Spd] modifier, 20% for [Spd]x2, and so forth. Thus, final speed for standard Impulse Engines will be (7.5+0.375*Mk) + N*0.1*(7.5+0.375*Mk), where N is the number of [Spd] modifiers. This formula works up to Mk XII; Mk XIII items are treated as if they were Mk XVI (16), while Mk XIV items as if they were Mk XXIII (23); for Combat and Hyper-Impulse engines, respectively adding or subtracting 1 Mk level from the final formula will give you a close approximation.
↑ Engines have a base 4.5 Turn rate; one [Turn] modifier will give them 4.8, and two 5.1, regardless of Mk level. Can appear twice on one engine, though Fleet Engines and some special engines have 3 or more innate or added [Turn] mods, and engines can be re-engineered to have more.
↑ Can appear up to 4 times on one Engine. As with [Spd], Mk XIII acts like Mk XVI and Mk XIV like Mk XXIII, so Mk XIII [Full] adds 19.5, Mk XIV adds 24.8. The number displayed rounds to the nearest tenth. For example, [Impulse Engines Mk IV [Full]] would receive a bonus of 10.4.
↑ Does not scale with Mk level. Previously Starship Inertial Dampers.
↑ Integrated into Efficient Impulse Engines, and can be found on Elite Fleet Efficient Engines.
↑ Integrated into Dynamic Reroute Impulse Engines, and can be found on Jem'Hadar Combat Impulse Engines [Rrt].

↑ Can be found on Elite Fleet Protomatter Engines. This modifier gives 0.15% Shield Hardness per 1% of Throttle up to a maximum of 15% Shield Hardness at full throttle.

An Uncommon Modifier will have one modifier suffix, Rare will have two, and Very Rare will have three. Rare and Very Rare can have multiples of the same suffix, and stacked suffixes are added together, not multiplied.

Ship shield modifiers[]

Uncommon Ship Shield shields will have one modifier, Rare will have two, and Very Rare will have three, Ultra Rare will have four. All Epic Shields have [Cp/Rg] as their default fifth modifier, though this can be re-engineered into a different modifier. It is possible for shields to have the same standard modifiers more than once. The following are examples of Ship Shield modifiers:

Engineering console modifiers[]

The majority of these modifiers are based on existing Engineering Consoles, which are listed in the "cf." column. Notes:

[HP] has no Engineering console equivalent. It scales the same as [ResAll].
[AuxPower] and the other power system mods currently give half as much power as they are supposed to, as do the [Pha], [Dis] and [Pla] mods.

[4] Common scaling: (Mk + 2) * 1.125%

[5] Uncommon and higher standard scaling: (Mk + 2) * 1.875%.
This scaling is used for [Armor], [ExpDmg], ½[ExpHit], [HP], [KCD], [KPerf], [Kp/Wpn], [PSG], [PSGRes], [Regen], [Will], [WpnCrit], and [WpnDmg].

[6] Critical Severity scaling: (Mk + 2) * 1.25%
This scaling is used for [CrtD] and ½[CrtX].

[7] Critical Chance scaling: (Mk + 2) * 0.3125%
This scaling is used for [CrtH] and ½[CrtX].

[8] Duration scaling: (Mk + 2) * 0.1875 seconds
This scaling is used for [ExpDur], [ExpDmg] (10 times the value), and [ExpHit] (5 times the value).

[1] Psionic Howl: When using certain abilities, 30% chance to deal __ Psionic damage (100% Shield Penetration) to all enemies within 15m of target Friend (or Self).

[2] Psionic Emissions: When using certain abilities, 30% chance to deal __ Psionic damage (100% Shield Penetration) to Foe.

[3] Psionic Consumption: When using certain abilities, 30% chance to deal __ Psionic damage (100% Shield Penetration) to Foe every second for 10 seconds..

[9] [Dire] scaling is as follows:
Bonus All Damage scales linearly at 5 + 0.15% Bonus All Damage per 1% of Health above one third of max health. Thus:

From 0 to 33.33% Health, it gives +5% Bonus All Damage

At 50% Health, it gives 5 + (0.15 * 16.66)% = 5 + 2.5% = 7.5% Bonus All Damage

At 100% Health, it gives 5 + (0.15 * 66.66)% = 5 + 10% = +15% Bonus All Damage.

[10] Bonus All Damage scales linearly at 5 + 0.15% Bonus All Damage per 1% of Health above one third of max health. Thus:

[11] From 0 to 33.33% Health, it gives +5% Bonus All Damage

[12] At 50% Health, it gives 5 + (0.15 * 16.66)% = 5 + 2.5% = 7.5% Bonus All Damage

[13] At 100% Health, it gives 5 + (0.15 * 66.66)% = 5 + 10% = +15% Bonus All Damage.

[15] [ShldCrit] scaling is as follows:
CrtD scales linearly at 0.15% Critical Severity per 1% of Shield Capacity percentage, for a maximum of +15% Critical Severity at maximum shield capacity.

CrtH also scales linearly, at 0.025% Critical Chance per 1% of Shield Capacity percentage, or one sixth that of the CrtD, for a maximum +2.5% Critical Chance at maximum shield capacity.

[34] CrtD scales linearly at 0.15% Critical Severity per 1% of Shield Capacity percentage, for a maximum of +15% Critical Severity at maximum shield capacity.

[35] CrtH also scales linearly, at 0.025% Critical Chance per 1% of Shield Capacity percentage, or one sixth that of the CrtD, for a maximum +2.5% Critical Chance at maximum shield capacity.

[dot-16] 1.0 ^1.1 ^1.2 The base damage does not scale with Mark level, but will scale with things that boost All Damage, such as the trait Aggressive.

[noscale-17] 2.0 ^2.1 This damage does not appear to scale or be affected by anything.

[18] This amount is affected by other things; sources are under investigation.

[25] X = (Mk + 2) * 0.625, rounded

[19] The drain resistance part of the [DrainX] mod was known as [Ins] during a previous skill system—standing for Starship Power Insulators—until Power Insulators was rolled into it. For a time after, [Ins] still appeared but erroneously gave Control Expertise; any old items with this problem were converted to correctly give Drain Expertise instead. It still appears on some Deflectors, and [Ins] is now aliased to [DrainX] on the exchange to ensure those searching for the old mod can find the new one.

[20] The [ShdHeal] mod was known as [Em] during the old skill system—standing for Starship Shield Emitters—and for some time after. It still appears on some Deflectors, and [Em] is now aliased to [ShdHeal] on the exchange to ensure those searching for the old mod can find the new one.

[21] Sometimes these stats are integrated into other special deflectors, including Elite Fleet Deflectors themselves.

[22] [ColCrit] scaling is as follows:
CrtH scales linearly at 0.04% Critical Chance per 1% of Hull HP, for a maximum +4% Critical Chance at 100% Hull HP.

CrtD scales linearly at 5 + 0.15% Critical Severity per 1% of Hull HP above one third of max hull. Thus:

From 0 to 33.33% Hull, it gives +5% Critical Severity

At 50% Hull, it gives 5 + (0.15 * 16.66)% = 5 + 2.5% = 7.5% Critical Severity

At 100% Hull, it gives 5 + (0.15 * 66.66)% = 5 + 10% = +15% Critical Severity.

[44] CrtH scales linearly at 0.04% Critical Chance per 1% of Hull HP, for a maximum +4% Critical Chance at 100% Hull HP.

[45] CrtD scales linearly at 5 + 0.15% Critical Severity per 1% of Hull HP above one third of max hull. Thus:

[46] From 0 to 33.33% Hull, it gives +5% Critical Severity

[47] At 50% Hull, it gives 5 + (0.15 * 16.66)% = 5 + 2.5% = 7.5% Critical Severity

[48] At 100% Hull, it gives 5 + (0.15 * 66.66)% = 5 + 10% = +15% Critical Severity.

[23] "It is no longer possible for crafted Deflectors ... to gain the [PvP Res] and [PvP Dmg] attachments. "

[24] "Resolved an issue that was allowing [PvP Res] and [PvP Dmg] mods to still appear on crafted Deflector Dishes."

[shhullcap-26] 1.0 ^1.1 The [HullCap] and [ShCap] mods found on the Fleet Colony World secondary deflectors give less skill than the normal modifiers, despite having the same name. Thus, a Colony World secondary deflector with "[HullCap]x2" will give X+Z Starship Hull Capacity.

[27] X = (Mk + 2) * 0.9375
Values in-game are shown rounded to the nearest tenth.

[28] Y = (Mk + 2) * 0.625 = ²/₃X
Values in-game are shown rounded to the nearest tenth.

[29] Z ≈ (Mk + 2) * 0.375
Not enough data points to be exactly certain.

[30] Can appear twice on one engine, though Fleet Engines and some special engines have 3 or more innate or added [Spd] mods, and engines can be re-engineered to have more. After calculating the base speed for the Engine's Mark level, the game will add 10% for one [Spd] modifier, 20% for [Spd]x2, and so forth. Thus, final speed for standard Impulse Engines will be (7.5+0.375*Mk) + N*0.1*(7.5+0.375*Mk), where N is the number of [Spd] modifiers. This formula works up to Mk XII; Mk XIII items are treated as if they were Mk XVI (16), while Mk XIV items as if they were Mk XXIII (23); for Combat and Hyper-Impulse engines, respectively adding or subtracting 1 Mk level from the final formula will give you a close approximation.

[31] Engines have a base 4.5 Turn rate; one [Turn] modifier will give them 4.8, and two 5.1, regardless of Mk level. Can appear twice on one engine, though Fleet Engines and some special engines have 3 or more innate or added [Turn] mods, and engines can be re-engineered to have more.

[32] Can appear up to 4 times on one Engine. As with [Spd], Mk XIII acts like Mk XVI and Mk XIV like Mk XXIII, so Mk XIII [Full] adds 19.5, Mk XIV adds 24.8. The number displayed rounds to the nearest tenth. For example, [Impulse Engines Mk IV [Full]] would receive a bonus of 10.4.

[33] Does not scale with Mk level. Previously Starship Inertial Dampers.

[34] Integrated into Efficient Impulse Engines, and can be found on Elite Fleet Efficient Engines.

[35] Integrated into Dynamic Reroute Impulse Engines, and can be found on Jem'Hadar Combat Impulse Engines [Rrt].

[37] Can be found on Elite Fleet Protomatter Engines. This modifier gives 0.15% Shield Hardness per 1% of Throttle up to a maximum of 15% Shield Hardness at full throttle.

[CD-38] 1.0 ^1.1 ^1.2 [EngCD], [SciCD] and [TacCD] give 0.75 Engineering/Scientific/Tactical Readiness per 1% of total Shield Capacity percentage across all four shield facings, with a maximum of +75 when all shield facings are at maximum capacity.
