ToME: the Tales of Maj'Eyal

The title basically says it all. My adventurer had both Unstoppable and Swallow talents, used Swallow on himself while still under effects of Unstoppable... and died.
Screenshot of the relevant chat log is attached.

P.S. Thinking about the silly mental image of the Krog eating himself made me giggle, :>

Yeah swallow's instant-kill is real weird since it bypasses instakill immunity if the enemy's health is at 5% or below. There's a reason it's disabled on enemies.
