Warrior is strong class in game which is loved by many players. Most players are not clear about what skill to get with their level (cabal alz) up. So we have to see skills in pve and pvp.
First pve skills is basic for your character, once you have level up you can put them high as you could. Such you can keep spiral of doom, whirlwind and seismic wave at level 9. And you need to keep soul blade, iron skin, aura barrier and down breaker on level 20. Then you will have good PVE build for your character.
Second part is pvp for your character in Cabal. For most skills we use you can choose and keep them at level 20. Such as bears vitality, impact stab, panic cry, fury shout, morale shout, bloody spirit, instant immunity, cats recovery, bears vitality and so on. As for upgrades, just do not get anything that gives you at rate and stuff like magic.
