An aim scroll is only to boost your accuracy even further. Anyway I have decided to go for a dex build besides what rokaraged said. Because the added stats are in percentage so I wanna try out what a dex build will be like and I'll tell you the result as I go along.
Im actualy doing a 2handed sword dex build and its not going bad at all, never miss a single hit and also lots of dodge if you have good equips and the scrolls.
I have to agree that a dex build does have some advantages and I have posted the outcomes of a 25 Spr Full Dex build at level 59 somewhere on the forums but since rokarage's findings about Str came out, I've decided to stick to my 25 Spr 5 Dex Full Str build.
