The rune plateskirt is a plateskirt made out of runite. It requires level 40 Defence to wear. The rune plateskirt is identical in function to rune platelegs, but is 1kg lighter in weight.
It can be created with the Smithing skill by using 3 runite bars and a hammer on an anvil; this requires level 99 Smithing and yields 225 Smithing experience.
Rune plateskirts can be bought from Scavvo's Rune Store in the upstairs of the Champions' Guild, Seddu's Adventurer's Store in Nardah, or the Bounty Hunter Store in Edgeville. Runite legwear can also be obtained as a rare reward from the Crystal chest, with female characters being awarded a rune plateskirt instead of rune platelegs.
Along with the rune platelegs, this is the best bar-per-alch item in the game. If smithing for money, rune platelegs and plateskirt will give the best value for each bar.
