1. Soulshots double your's damage on regular hits. Pull it on your's shortcut bar and try pressing that "F" key. Each ss charge last one hit. If you whant your's ss to spam right klick it on your's shortcut bar.
2. Higher lvls of those crystals can add special abilities to higher grad ewarpons. Try selling your's in larger towns for probably around 30-40k (if that crystal is stages 1-4). Dion will proably be a good place to sell those
3. Pull them to the garbage can icon on the bottom of your's inventory window. And the press "ok" in the pop-up.

I say hold onto it....You might find a better use for it later in levels just stick it in your warehouse, as a new player my advise is to hold onto all resource drops (bone, animal skins, coal, stems, etc)
If the soul crystal hasn't been leveled (indicating *stage 1-13*) delete it. It's worthless. You get them for free when you start the soul crystal quest.
