STR = Minimum required for weapon
ESS = 8 (+minimum needed for relics)
WIS = Enough to use Essence Relics
CON = 400 hp every 10 levels (without buffs)
DEX = Everything Else

Common PvE Build
This is a build that a lot of players use. It allows them to level fast while grinding, but you are extremely weak in PvP. Anyone with a bit more Dexterity than you can probably beat you silly.

STR = Everything else
ESS = 8 (+minimum needed for relics)
WIS = Enough for Essence Relics
CON = 400 hp for every 10 levels (without buffs)
DEX = Minimum required for weapons +3 to +5 more

Common PvP Build
Many of the people who want to PvP out there will use a build similar to this. They will be able to beat almost all of the pure STR people unless there is a significant level difference (~16 or more levels I guess). They will level slower than someone with a pure STR build though. A lot of people who reset from a pure STR build will often use a build like this.

STR = 5 STR for every 3 DEX
ESS = 8 (+minimum needed for relics)
WIS = Enough to use Essence Relics
CON = 400 hp every 10 levels (without buffs)
DEX = 3 DEX for every 5 STR

Balanced Build
I think this build is horrible for higher levels. I have seen warriors that can barely tank 1 mob using this build. At higher levels, they will receive much more injuries while leveling up. However, they can be extremely annoying to deal with in PvP. They have decent defense and dodge and 9 dragons goldcan deal a fair amount of damage to most people. If they fight someone close to their level, they have a high chance of winning if their skills are trained.

Accessory Setups
Accessories are important for warriors. They can be used to help them save many chi points that could have been put into essence for something else like constitution. The main goal of any warrior is to achieve high damage and defense with a fair hit rate. Using clothes that boost stats such as maximum life can help reduce the number of points you need to spend in constitution. Conserving your stat point usage is important in making a strong warrior.
