Hi! You can automate the use of SoulShots by right cliking on them after you have put them in the bar. If when attacking there's nothing happening, then maybe your weapon doesn't use D SS. You should use SS with the grade matching your weapon. Hope my explanations will help you! C ya!
Like MrPinch said make sure the weapon your using is the same grade as the soul shots.
However, if your a new player, I would strongly advise you not to buy soulshots. Its a money pit new players cant afford. You will need all the adena you can get your hands on to equip yourself decently at lvl 20 for D grade.
Thanks all I have the icon on my toolbar, and am using the Kukuri(sp..???) dagger.I tend to get excited (hehe) in the midst of fighting, and hit the wrong key...so it might just be me. I know my ex-pet wolf got real tired of me pressing his attack key before mine..lol
I'm at lvl 23 -1/2 :p
Thanks again Theran
