Y'm-bhi

Fallen explorers reassembled as shambling dead — your own dead teammates can come back as these. Grabs crew members; a well-timed hit breaks the grab.

No community measurement for this one yet. Bosses and several of the unkillable horrors have never produced a reliable HP figure — we leave the field empty rather than invent one.

What the codex says

The bestiary is careful about this one: the Y'm-bhi are not a people but a class of being — mortals reshaped by methods the manuscripts don't pretend to understand. Many of them were explorers.

Standing orders

This is what a teammate becomes if the jungle gets the body first. Revive fast with Ammonia Salts, or haul the body to the ox-wagon. Losing a crewmate twice is how runs end.

Y'm-bhi questions

How much HP does the Y'm-bhi have in The Mound?

Nobody has produced a reliable HP measurement for the Y'm-bhi. We leave it blank rather than guess — treat it as a threat to avoid rather than a fight to budget for.

What happens if a teammate dies in The Mound?

Revive them with Ammonia Salts or carry the body back to the ox-wagon for the priest. Leave it too long and the forest claims it — the explorer returns as a hostile Y'm-bhi.
