Here's A guide incase you don't know what build your class should be.
DEX - Adds Aim and Evasion.
STR - Adds physical damage.
INT - Adds magical damage.
SPR - Adds critical rate and SP.
END - Adds HP, defense and block rate.
Archers,
Mostly need is DEX, END is almost useless, or full dex
DEX and SPR are pretty good for an archer. Fighter's with an axe would miss alot.
Adding 25 SPR for the critical rate, and rest into DEX. You shouldn't put more then 25 SPR cus the critical rate lowers after 25 SPR. 25 SPR = 5% Critical rate.But you really want neeed spr because crit suits provide that.
For bow users DEX/SPR/END is best build. Pure DEX. :3
And for xbow users DEX/STR is best build ^^
Mages,
The magical damage for mages is based on INT. Do not put STR on a mage, it's useless and epic fail.
Put some DEX for aim/evasion and SPR for magical defense/critical rate.
Wand, gives more Mdmg but less Aim.
Staff, gives more Aim and less Mdmg.
Fighters,
They can use almost all stats. Except INT. Same as a mage, Epic fail!~
If you choose to be a tanker, the pure END build is the best, together with some DEX to higher your Evasion.
You can also be a DD (Damage Dealer). For a DD, the pure STR with some SPR is pwnage :3 your def sucks without +9 armors tho. ^-^
You can also be a hybrid and mix all the stats up. It's funny :3 (Just not INT.. lol>_>)
There are alot of weapons for fighters.
Two handed Swords, One Handed swords, Axe and there's a shield for more def.
The two handed sword is mostly for the hybrids when the One handed + shield is for the tanker and the axe is for the DD.
One handed swords got low Dmg with high aim.
Two handed swords got medium on everything and high on smexyness :3
Axes got low Aim with high Dmg.
Shields are for One handed sword users, it adds more def and block rate.
Clerics,
There are many builds for clerics,
Critical/Support Cleric is a full SPR build. (mostly used for supporting your party)
Tank Cleric is a full END build. (Higher HP + Def, bigger chance of surviving in a AoE party)
If you're a boring person that got a fobi of partys,
you can put DEX/STR and END in your build for soloing.
DEX and STR will help you kill fast and the END will keep you alive.
Clerics use Shield + Mace or hammer.
The mace gives you more aim and less dmg
while the hammer gives you more dmg with less aim.
