Amea/YMMV

Alas, Poor Villain: Mish and Valde
Nightmare Fuel: Oh yes. Special mention goes to the prologue, which begins happily but ends with rotted bodies littering a field under a bloodred sky as a towering figure (later revealed to be Mish) groans out Amea's name.
Player Punch: Poor Garrick.
That One Boss: Valde, whose dodging can get annoying, but after him comes the Master Eye, really big, attacks that can hit you consistently...
