Resistance and impedance

Electronic warfare resistance and remote assistance impedance comes in many shapes and forms, some through innate ship bonuses or tactical modes, others through special modules. It is an attribute that reduces the effectiveness of electronic warfare and remote assistance modules.

Resistances and impedances

On a basic level, the difference between resistances and impedances are that resistances help you by making hostile effects (like electronic warfare) less effective, while impedances make friendly (such as remote assistance) effects less effective.

There are a variety of attributes that affects the effectiveness of electronic warfare and remote assistance.

Type	Group	Effect
Electronic warfare	Sensor Dampener Resistance Sensor Warfare Resistance	Reduces the effect of hostile Remote Sensor Dampeners.
Remote assistance	Remote Assistance Impedance  Remote Electronic Assistance Impedance	Reduces the effect of Remote Sensor Boosters and Remote Tracking Computers.
Electronic warfare	Weapon Disruption Resistance	Reduces the penalty from Weapon Disruption .
Remote assistance	Remote Repair Impedance Remote Logistics Impedance	Reduces the repaired amount from Remote Hull Repairs, Remote Armor Repairs and Remote Shield Boosters.
Electronic warfare	ECM Resistance	Additional chance to avoid being affected by ECM Jamming
Electronic warfare	Stasis Webifier Resistance	Reduces the slowdown effect of hostile Stasis Webifiers.
Command Burst	Electronic Hardening	Reduces the effect of hostile Remote Sensor Dampeners and Weapon Disruption .
Electronic warfare	Capacitor Warfare Resistance	Reduces the capacitor drained by hostile Energy Neutralizers and Energy Vampires.

Examples

Below are some examples of ships, modules or scripts with such resistances and impedances:

The Confessor and other tactical destroyers have the information in the Traits tab as it's not always applied to the ship depending on their tactical mode.

For ships like the Avatar and other titans, the effect is always there and can also be found in the Attributes tab.

Modules like the Siege Module II and Triage Module II also apply certain bonuses and drawbacks in the form of resistances and impedances, which you can seen under the Attributes tab.

The Electronic Hardening Charge (used in Information Command Burst modules) will not only boost your sensor strength, but also give the recipient a moderate electronic warfare resistance to remote sensor dampening and weapon disruption.

Understanding the values

As with many attributes or bonuses, it can sometimes be difficult to understand how their effects are calculated. Sometimes attributes that are very similar in name, have the same functions, sometimes they do not. Sometimes the same type of effect can be shown as both a positive or a negative bonus, while functioning the same in the end.

Resistances

Resistances are often presented as negative bonus values, ranging from -0 down to -100%. The value represents how much of the effect is removed, so a -70% resistance bonus reduces the effectiveness of electronic warfare by 70%. This attribute can sometimes be presented as a positive bonus value (for example in the traits tab of a tactical destroyer). The bonus works the same though, despite it being a positive number, in that the +66.6% resistance bonus reduces electronic warfare effectiveness (in this case, weapon disruption and sensor dampening) by 66.6%.

ECM Resistance works differently from other electronic warfare resistances, in that they give a chance at avoiding the effect of enemy ECM jammers. This can best be explained as a flat "chance to fail" that is checked before anything else. This is an exception to how all the other resistances work due to the fact that a ship cannot be partially jammed. An ECM Resistance bonus of 100% means they cannot be jammed at all, the ECM module will simply not activate on the target. This can be a useful method in PvP to verify that a certain ship has entered triage or siege mode. A partial bonus of 50% would first roll the 50% chance of simply resisting the jamming effect right away, failing that it would then proceed to check whether the ECM strength of the hostile jammer is enough to overcome the sensor strength of the target.

Worth noting is that partial ECM resistance is currently a theoretical scenario described in the Reworking Capital Ships: And thus it begins!  devblog, there are currently no such semi-resistance bonuses in the game, just 100% bonuses giving full immunity through Siege, Triage and Bastion modules.

Impedances

Impedances are also presented as either positive bonuses (often in the case for ships' innate impedance values) or negative bonuses (commonly done for impedance bonuses from modules). If the value is a negative value, like a -60% impedance bonus, it means that any incoming remote assistance of that kind is reduced by 60%. If the value is a positive +80% impedance bonus it means that they will lose 80% of the positive effect of the remote assistance, in effect only gaining 20% of it.
