You get XP per objects avoided so that the longer you stay on OSRS gold your toes the faster he throws things at you thus a faster xp rate. But of course to acquire this quicker xp speed you need to be quicker at dodging the objects thrown, watching as they are coming at a faster speed. If you can not stay standing for more than 10 min the xp rates won't exceed normal xp rates on your level so only really'skilled' people that can remain standing for a significant quantity of time will recive really large xp rates.

. Still requires a lot more consideration. The great orb project is a fantastic miniature game but it does not raise xp prices. We need a way to alter it so persenal score gets incorperated and people get xp predicated on performence. . .more to come

Structure: A mystery across the lines of catapult cunstruction. Randomly created structure you need to build. The quicker you build the more xp you get. Jagex would really have to work hard in their arbitrary creation of them. . .no 2 constructions ought to be the same!

Crafting: You are provided a rnadom picture you have you have to paint a certain image on a pice of armor. The closer you manage to paint the armor such as in the case provided to you the better that the xp reward you become. An issue I see is that the impossiblity of coming up with buy RuneScape gold random pictures; a few fansite can eventualy make an image database. (this migh be deleted it sounds somewhat absurd and unrelated to crafting)
