Death hat

Death hats, mentioned in the Behind the scenes May 2011, are future content expected to be released mid-May 2011.

Article from the Runescape Behind the scenes May 2011:

''Who doesn’t like hats? Hats are great! They keep the sun out of your eyes, warm your head in cold weather, can be worn at a jaunty angle, thrown in the air and left to just simply exude general hat-ish qualities. Come mid-May, they’ll also be able to show off to the rest of RuneScape just how many players you’ve PKed in the Wilderness and defeated in the Duel Arena.''

''The wildstalker helmet will track your Wilderness kills and the duellist’s cap your victorious duels, each morphing into ever more terrifying styles as you reach certain milestones. Both hats will give you the ability to transmogrify into a commemorative statue, upon which other players can behold your various PvP stats, and they’ll also let you perform a suitably fear-inducing emote. Don’t fear the reaper; fear the owner of a fully morphed death hat!''
