RuneScape players can claim five cosmetic rewards from the RuneScape Easter event 2013. To claim these, go to north Falador and speak to Memstix.
The cosmetic gear was released with the March 12, 2013 RuneScape Easter Event. It is available both to free RuneScape players as well as to members. Speak to Memstix; right clicking Memstix bypasses a lot of chat if you want the rewards without the lore/world wakes spoilers.
Three of the five items are cosmetic guthixian gear for the head, body, and legs. If destroyed, they can be reclaimed from Diango.
RuneScape players also get an emote; Butterfly Dervish. This emote can be easily accessed by sorting emotes to "holiday."
THe last item is a customization override for two handed swords. The Sword of Edicts override can be activated and disabled using the customization interface and selecting main hand weapon overrides, then scrolling down through the list.
