yh Jason if you base the cape on a 99 skillcape it wont be tradeable and you wont be able to drop trade it either, the cape wouldnt be hard to make you just need to change the graphics of a 99 skillcape to a colour that you want and a big money symbol on it but this cape should be given in a shop that only certain people can get to so maybe put it in a place like digsite so that people have to be teleported in there to buy it then teleported back out and if you set it on a 99 skillcape they wont be able to trade or drop trade it, this sounds like a good addition plus ive donated 3 times :p
