Alot of people seem to have a problem with understanding this so here is how to make one.

Say for example we want to make a ring we firstly create a normal ring then change the shape to 141 you then have to set the dura for the exp ammount this is devided by 10,000 so if the dura is 20,000 u will get x2 exp

So a x2 expring would be
SHAPE 141
DURA 20000
So a x5 expring would be
SHAPE 141
DURA 50000

For a candle or exp weapon you need to set the anicount to 141 instead of the shape

So a x2 expcandle would be
ANICOUNT 141
DURA 20000
So a x5 expcandle would be
ANICOUNT 141
DURA 50000

Please bear in mind if you have the dura too low it will decrease the exp earned so having 5000 dura would half the exp earned

Items can stack so if you wear 2 2xexp rings them you will have 4xexp
