"Three Strikes"

This longsword +2 has been passed down from generation to generation of elves, first discovered by Kiyarniar Buentiejal, famed founder of the wood elves Trangull Drevo. Rumors say that it was given to Kiyarniar by Corellon Larethian.

The owner can go below 0 hit points twice wielding this weapon, but on the third time her hit points reach 0, she finally dies, skipping stabilization attempts, etc.

This sword is also imbued with wounding.
