some remarks:Evolve is an ability generally costing :timeEgg Eye generates an Elite Face whereas the Elite Eye generates the Normal Face...
AHH! A big typo! Thanks for pointing that out, both of you.
Hatch is the ability currently in the game which is time, the only one of it's kind in the game, so i don't see a 'generally costing time' factor.
Darkness so far has been the only suggestion so far, with the reason being: fear of the unknown (very close to that).
What do you think fits?
