Eternals currently feel underpowered and the Xenonaut side almost never struggles with morale, even when facing psionic aliens. If Eternals passively reduced Xenonaut morale every turn by a small amount, they would be more oppressive. The "focus mind" ability can provide counterplay, or the player can just kill aliens faster. The amount of morale lost should be affected by bravery, to make mind shields more useful, and it should be pretty small to not make it tedious like the dread aura in Xenon
I agree. I have edited your post to build on your idea. Lets add a dread aura for intimidating aliens. Reapers should be the root source of dread aura then Ethernals should absorb all the features which lesser aliens posses (dread aura of Reapers, clocking of Wright, regen of Sebilians, psionic attack of Psions ... )
So, the Dread aura has the same 3D range as grenade (include damage fall-off rule ! ) and works as an invisible permanent cloud around the alien.
