Are these couple sentences worded in the best way?

FYI- Hakuun is the shaman and Grguch is the chieftain. While his other companions continued to battle the orc soldiers, Drizzt engaged Hakuun and ultimately slew the shaman as well as the shape-shifting Jack. Bruenor fought a vicious duel against Grguch, which ended with the orc chieftain disemboweled and decapitated.
