Easy Combat Level Ups

Have u ever wondered how people get their combat lvl up so fast? Well here is one way. First u gotta be a member than u go to Relleka and find rocks. Big rocks. U find them on the end of Relleka. Lvl 13 Rock Crabs appear and randomly attack u. They may seem nooby but u gain 200xp or more per kill. Another way is killing Hil Giants. That is all. Also if this takes too much time for u high lvls go to Pvp worlds or the Wilderness.
