Runescape what do you get when you complete all the quests on f2p?

Quite simple. Get membership and bash some Dagganoths and King Black Dragons (KBDs). Try completing all of the quests! Almost impossible... Complete skills and get skillcapes, and the world of RuneScape is 10x larger than before!

Sail of to Karamja, and go for a hike in Camelot, and visit the one and only Grand Tree to complete the Grand Tree quest!!

I've been addicted to RuneScape ever since receiving membership. Good Luck!
