Amulet of the Broken Wake

A small brass amulet shaped like a cracked wave, set with a splinter of black shipwood that’s always cold to the touch.

Crew’s Last Breath (1/Day). When you or an ally within 9 m (30 ft.) would drop to 0 hit points, you can use your reaction to have that creature drop to 1 hit point instead. This works only if at least one other ally is within 9 m (30 ft.) of that creature.

The amulet regains its expended use when you finish a long rest.
