nice win! Good points on rewind, I mostly agree. Theres always going to be balance problems with spells that generate resources and don’t exhaust. Rewind is obviously powerful for this reason, but so is meditate and even longstrider. Meditate is arguably the biggest problem of the three, but it’s such a glue spell that i hesitate to touch it. Exhaust would be effective but I don’t want to put exhaust on too many spells.
I have always had too quick of a trigger finger to nerfing powerful but fun content in “card or card-adjacent” games so I’m going to refrain from touching any balance atm.
From looking at your build, honestly what might be the real problem is 2x whirlwind being too efficient. Things like rewind are only as good as your ability to clear the board of enemies, so maybe whirlwind is a bit too efficient specifically when you have two of them. Earthquake is 2x whirlwind in one spell, but with an extra 1 MP and 2 AP for its efficiency, and it’s also really good. Maybe whirlwind should cost 1 more mp or ap. I could also make it more rare, theres an entirely invisible rarity system and i think whirlwind is relatively common (earthquake is relatively rare).
