They could have "battle personality" when they step into a combat, extra "spicy-ness" comes out of them. Making the battle feel more engaging and immersive.
I still have no idea what are you talking about ...
Like while Lae'zel would be yelling "for Vlaakith" while cuting her enemies head off ...
Karlach would be yelling "Zariel will not get me" while cuting her enemies head off ...
Is that the big change?
