After reading the trait and abilities a little bit more by somehow i find a shitty build around only aura and buff skill only and you even dont need partner to deal dame, just need a some migation aura, reduce enemy dame aura, heal per turn aura, trait and the core dame aura skill, a nether aura skill that deal 8% max Hp as poison dame, but with this kind of build we also need more max mana and mana regeneration, and i also use a weapon have the skill that regen 1.5 ( can be 2.0 mana when have mastery ) when in battle i will regen 4.0 mana per turn, may enough to sustain this build
Does the build good? Nope, it kinda low dame( but if you use mastery increase the poison dame every turn it can make some high dame, i once make the boss take 132% max Hp every turn as poison dame :v )and only tank, kinda boring just only spam the mana regen skill every turn, but it fun when thinking to make a shitty build even though that isn't effective
