Doubly so when said sword has a higher initiative than you. And has teleporting powers. And uses those powers to put you in between the group of monsters (so that you are in a 'target-rich' environment) before you know what's going on.
And then it turns out that the monsters managed to get a higher initiative than you -- so they hit you before you have a change to strike them.
Luckily the sword could also teleport me out of the melee, next to our healer.
