*Potion reserach 10 for more effective pot recovers,
*Sword mastery is useless, workin with one handed swords and its not necesarry if you wont use twin edge or something.
*Demonic + Fire Expansion 5 lvl is good but if you have very good cast. If you don't use mjolnir or have no good dex/int or spell. You can also can use 1 lvl demonic +5 lvl fire expansion to cast it faster. Dmg is so similar.
*Crazy Vine you will need it. Make it 1 LVL max, it removes debuffs by mvps. Like fallen bishop's pneuma or if some mvp or monster hide from you and you can even dmg them with crazy vine.
*Blood sucker is not necesarry but useful for some situations you can keep it. (Personally I never use it, just thorn trap and crazy weed helps me a lot)
Rest of all skills are fine. Geneticist is always have free skill points to give, you don't have to worry too much
hmm I have level 6 Crazy vines, Level 2 summon Flora
