I thought of this and before removing debug mode I made sure to hit the -4 nail damage like 20 times. Currently I am trying on a new save file that never has had any mods so it is clean. Oh and for anyone thinking I want credit for discovering a glitch, that is wrong I actually am sad because my save file is now corrupted with an infinite damage nail and now the game is too easy

it also doesnt let you damage mawlek during scream so it wouldnt be useful
