My Deadly UB: (note this is with ai buying citadel upgrades)
scaled helm + banded armor
On first return unbreakables
Second Return: duelists treads + Ancients Wraps
Third Return sell scaled and banded; buy ancient armor and ring of the ancients
Favor Item: Venom Stone
2. Stats/inner beast
3. ^^ watever you didnt get
5. Post mortem
6. foul grasp
Remaining levels max out inner beast and spit first. Then get stats (you need stats for the HP boost).
Advantages over standard UB build: Massive DPS, lots of mana for the ability to spit/skirmish. Low health but this is countered for by high speed.
(note i still reckon that venom stone needs a nerf lol)
