Attack pattern conditions for enemies are ignored in EasyRPG player. (RPG2003)
This can be tested near the beginning of Vampire Chronicles 2 when battleing the Elementar on the top of Drakes’ tower. Prior to this battle the main character reverts to Level 1 and is powerless against this foe, so the conditions are set so that the enemy always skips its turn until another character is switched in mid-battle.
In normal RPG_RT play this works fine and the Elementar won’t use any damage-inducing attacks before the second phase. But EasyRPG player ignores the Switch condition which results in an impossible-to-win battle and instant gameover.
