|| banishing gives you the carefree melody (3 notch) that has a chance to negate a hit taken, and the chance to do so increases for the more consecutive hits you've taken without it activating, and resets the chance when it does activate. its only really useful if you use a mod to reset the rate or manually (ridiculous to do so) get hit to boost the rate. its mostly helpful for no hit bosses or REALLY hard modded ones ||
|| defeating nkg gives you the upgraded grimmchild, same 2 notch minion that just passively deals dmg, not much to say. ||
|| carefree is great in some gag modded bosses, and alright in hitless. grimmchild is only good for no nail challenges. pick either or, if you're pc theres a mod that gives both anyways if you end up needing to do said modded boss or a no nail run ||
