Esma- dex dependent or not

i do believe it does get more powerfull and as far as costs go once you get to about 90 you got like 2000 sp and the cost to estun/esma stuff drops to about 50 per shot which isnt bad at all and the regen rate is pretty quick. THats all based on if you have 99 int and a few int gears that are easy to get equipped.
