Optional Training (Train these last if you have the points)

Chain Spear Tiger (Optional Max)
Very quick series of spear moves which boosts your chance at delivering critical damage

Side note on criticals:
Criticals are calculated based on your base str value, so if you're an int build criticals are probably equal to you doing your max damage so it's not such a big deal, but on an str build the more str you have the higher the critical difference will be compared to your regular damage.

Wolf Bite (Optional Max)
A good quick skill that doesn't particularly excell in damage bonus, but does increase your damage, I wouldn't really use it myself, but some people think it's a nice little extra boost of damage, personally I feel if soul spear, chain spear, and ghost spear don't do the job, you must have be fighting mobs or players too strong for you http://www.silkroadtavern.com/strategy/guide/439
