so if your eating good meals and upgrading armor, burial chambers arent too terribly hard. honestly the biggest damage sponge in one is the ghost early on. you'll want a mace and shield for everything else parry and smack and most things die in 2 swings.

these are meant to be mini dungeon crawls afterall.

once you got the kinds of materials you need to make a Stagbreaker hammer, it helps with skeletons and their spawners to be cleared more easily.
