sometimes you can glitch the hp, so you won't take any damage. It doesn't work every time, but I found that by taking some damage and then healing to full go find another heal and spam it, it makes the purification ending easy.
great game but I do wish that I didn't have to beat the game to go back to the nsfw there should be an option that after you did it once you can go back straight back to the nsfw content.
