For the love of god, please, don't make every single action or basic attack use spirit, it makes you useless with no items to recover spirit, also, nerf the withc man.
Thanks for the advice. The way I saw it, the spirit should limit the player's actions—for example, so they don't constantly run around or engage in unnecessary battles. The levels are designed so that the player can effectively avoid fighting at all, right up until the act's "boss." I certainly don't want players to memorize enemy behavior patterns, but rather to be a little more attentive.
I'm not entirely sure who you mean by "the withc man." If you're talking about the Bone Keeper in the tavern, his most annoying ability is that he permanently breaks a character's bones with a small chance. Otherwise, he's quite frail. As for the Witch Head, she's more like Mr. X from Resident Evil, but with a fixed route. I simply added the ability to kill her so players don't feel completely helpless.
