Mortar crumb
From the rim of a murder-hole, where the whispering has gone on long enough to wear the stone.
Vendor trash. Nothing in the game wants it: no recipe, no enchant, nothing to wear. Stacks in one inventory slot. Vendors pay 269 coins for it.
What drops it
Murder-hole whisper
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.
