I am currently at 314 of 326 creatures and have hit a brick wall on how to get the remaining 11. The creatures I am missing are:
Ancient Ent - I encounter them as enemies but can not extract cores from them. I might have accidently released it at one point but I am not sure.
a creature with the Revulsion ability
a mummy with the Death Beckons ability
a phoenix with the Final Breath ability
Pumpkin King - I have to wait for this one
Has anyone any hints on how to get these?
