Scarred Slab of Marble

A rune-ringed monolith that takes your wounds in exchange for stone flesh.

A once-beautiful marble slab, some 30 feet tall and half again as wide, ringed by carved runes of union, protection, consumption, and sacrifice. It cannot be moved.

When you pry off a chip and swallow it while standing within the runes, your flesh becomes stone and your DEX drops to -2, but the slab suffers the next three instances of physical harm in your place.
