156) 3.5e

Choker of the last stand:
When activated, this crimson band of what looks like stained silver will absorb your soul, using it to fuel your body as a machine of war, allowing you to fight well into your negative hp, the price you pay for this power is that you perish after combat ends, your soul is now the property of [your worlds god of war/conflict]
If you are beheaded before combat ends, and the choker removed, there is a 50% chance your soul is not sent away.
