Gravewax lump
Pale, soft and faintly greasy, and best not asked about.
Vendor trash. Nothing in the game wants it: no recipe, no enchant, nothing to wear. Stacks in one inventory slot. Vendors pay 175 coins for it.
What drops it
Tomb stalker
1 in 5
Rolled on its own rather than from the loot table, so it takes nothing away from anything else that falls off it.
