Field notes
The page says Chrome and Edge can watch a desktop save file and update the tracker whenever the player rests at a bench; console players can mark progress manually. Its charm and combat sections calculate nail damage, boss hits, soul, healing, and spells, with matchups against 180 enemies and bosses including Godhome. The site attributes its numbers to the wiki and says it uses the game’s rounding and official translations.
