Use the concentration skill Luc. It'll help your combo recharge faster. What orc chief? Are you rescuing Wilbur? You could level up a bit in some other area first. Don't use too many runes to level up your skills either. The recharge time will become rediculous.
My Gladiator does something like this with the average mob:
Multi-hit first, 4xhard hit combo and another multi-hit after or fist of the gods to finish off bosses. All on keys 6,7 and 8. If anything is left alive, its a dragon. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
Egin, there are no particular 'finishing moves' but the combat skills give some awesome crowd-control skills. The combos simply allow you to do up to 4 combat moves at once, 1 after the other but giving a longer recharge time.
Hope that helps.
