The Guardian Class are known as the warrior class of the Rohan. The complete opposite of defender, their power lies on their offensive attacks. Now here is a guide for Guardian. Just go through.
Base Stats
Strength Build: Most people follow a 3:1 strength to vit build. This is a good starting point as you will do pretty decent damage with decent gears as well as have the HP boost to survive while grinding. However, as a strength build you still need to accommodate for dex in your build so that you can hit mobs every hit without missing.
Personally, I stayed with base dex all the way up until level 60 where I was able to use four Wings of Solemn Death (15 strength, vit, dex). I made up for my lack of dex by utilizing level 1 Invoke (20% boost) and dex accessories. If you are not a member of the Exchange Market, I suggest still using dex accessories so that if you ever do get your hands on a Wings of Solemn Death, you do not have too much dex (unless you wish to have it that way, I know many Guardians who do).
Dex Build:
This build is often referred to as a cash-user’s build as it is incredibly gear-dependent. I don’t suggest using a full dex build, but instead a 3:1, 4:2, 6:2 dex to vit stat distribution.
Many people just put in 1 or even 0 points of vit per level in order to maximize their critical hit damage, but remember this: you will be a crit-based build and should have little problems taking down players as high above you as 5-10 levels (Rohan powerleveling, Rohan gold)depending on your level and weapon.
Hybrid Build:
This is the most powerful build for a Guardian there is but it’s very gear-dependent. Without the proper weapons and armor, you will be squishy (lose more pdef than you think you would from the strength/vit you lose per level) and an easy target to take out and if you don’t have the proper weapons then you won’t be taking advantage of what the hybrid build offers — steady base hits with devastating crits.
The majority of your stat points should still be going into strength, with a point or so going into dex every level. 2:1:1 strength-dex-vit or 3:1 strength-dex is the preferred build here. Unless you are very experienced, I suggest the 2:1:1 simply because as a new player it is hard to survive without any vitality at all…especially if you don’t use EM or have high level mains where you can farm the necessary boss drops.
