Electrical Damage has the added benefit of dealing X2 damage to and stunning any Corpus enemies that do not have shields active. MOAs hit with this damage type that have had their shields dropped will stop moving for approximately one second, but will still be able to fire their auto-lasers. Even though the electrical effect shows up on Grineer and infested it is has a relatively low chance to stun them (although they will sometimes use a different death animation if killed with electrical damage). The exception being Vauban's Tesla and Volt's shock which stuns medium Grineer with every shock.
