For the first time I think I've stumbled upon an entirely broken build in Buriedbornes, a randomized permadeath turn based dungeon crawl.

I picked Moon Queen as a class, which does HOLY and STR damage. She also has no control of her moves, but they activate automatically in order from right to left on the skill bar, basically allowing you to use 4 moves that don't end your turn, and then use a final attack, so you can use all of your skills on one turn, then just wait for cooldown. In addition, since she has constant confusion, she deals double damage and has double HP. She can also crit on her heals.

You can give charas several buffs or permanent extra effects before you start the game, and I focused it on extra heals, limit breaking, finding good items, and boosting HOLY stat. So throughout the dungeon crawl I shaped my playstyle around this and basically ignored STR entirely, and it worked so well because the end result is now causing me to instakill every enemy on turn 1 by healing myself!!!! It's all centered around an item that deals health I heal as damage (regardless of whether or not im at full health). And a skill that does the same thing. And they stack... It's ugly. There's more to it but. It's just so broken.

So my HOLY stat is well over 20,000, which serves as a multiplier for skills. My healing is at over 500%, which is multiplied by HOLY, AND the power of the healing skill you use. I have 3 healing abilities, of 5 total

Moon Heal: Scales off raw HOLY, super low cooldown, has an effect to trigger two heals so it does double damage and destroys enemy barriers as well
Angel Light: scales off of max HP (through the roof), and also boosts heal effectiveness, medium cooldown, also triggers a second heal
Angel Light: this one doesn't heal twice but reduced cooldown
Angel Army: heals damage enemies
Moon Blade: Attacks. Useless now.
