Wait until level 26. There is a lot of good eq at that level.

Get a decent gun (maybe Percussion weapon). Look for helm/armor of Force or Security are almost always solid choices. Ring I would get Infused Ring of Warfare (or Legend Ring of Assault or Ensorcelled Band of Brutality if you can afford). Amulet wear Infused Brooch of Assault (or Superb Amulet of Brutality if you can afford). Total cost somewhere about 45-50k I think, and should hold resell value.
