At level 500, Undead Slayers will begin to appear on your Fight List. These mangled corpses of other players are great for fighting at higher levels when living opponents begin to seem fewer and far between.

Unlike a normal Slayer, Undead characters don’t carry Cash and can’t be hurt. You'll be able to tell the apart on your Fight List as they'll have purple names and a small tombstone beside them.

Undead Slayers will only appear on your list when you've defeated all the regular Slayers, or there aren't many available. If your list is still full of Slayers for you to fight, the system won't generate Undead ones for you. Keep in mind you can only fight them so many times in a day before they melt back into the shadows and disappear, but not before you get your max daily Gamer Points!
