Ro Zeny can help you upgrade quickly. Blow - the level 1 available, an increase of percent ten rebuff skill in Talisman point when most vividly. This technique is great, it has the highest damage of all your skills and the reduction, which means that you will goal defense and other parts of your attacks for more damage, keep the boss all the time on top of the rebuff. It is the greatest.
Rapid crack - level 1 is available, from 25% increased damage skill points so well. This skill instant and deal damage with a heavy blow to refuse to deal with this large number of losses. It is the greatest.
Shadow crack - available at level 7, skill points increase rebuff by percent fifteen when maxed. Personally do not find this skill very useful, it lowers the damage of target a bit but takes one point five second to cast. You can use it on bosses to assist the tank but except for that there is not much use. Thorn crack - available at level 15, skill points decrease move speed by percent twenty five when maxed. This skill slows target, but takes one point five second to cast. When you have poison of slow this skill is pretty useless, except for stopping people from running in PVP, however oxbow is better for that.
