Devil Inside Trophy
Power up your General to a Demon.
Your general needs to eat three skulls. Skulls are left on the battlefield when you kill an opponent or some maps already have them, eating them heals your units and increases their maximum health. Eating three of them will turn any of your units into a demon, which gives them extra actions each turn.
This trophy can be unlocked on any level in any game mode. If you do the first level which serves as a tutorial, as soon as you’re told about eating skulls you can unlock this it. Simply select your general and have him eat three skulls over three turns (you have 1 turn because you still don’t have your 2nd sword), retreating behind your line of infantry after doing so to prevent the A.I from attacking him. The trophy will unlock after eating your third skull.
