Electrical
From FOnline: 2238 Wiki
The Electrical damage resistance is a combat statistic. Each armor has a special Damage Resistance and a special Damage Threshold for each damage type ; the Electrical one applies for all the damage done by electricity - Grenade (Pulse), YK32 Pulse Pistol and YK42B Pulse Rifle.
This damage resistance is modified mostly by the armor you wear, because of its Damage Resistance and Damage Threshold.
