loving the off-meta builds! a stealth wildfire build would be pretty entertaining imo, using assassin jacket and invis pots to get close and E in people's faces
I tried experimenting and i found that with the huge damage bonus of mage robe you just deal so much damage but you can switch the stalker hood for something like the royal helm so you can still land the E. Now using the 3rd passive of the fire staves you can cast both the helm and the E very fast so landing the ability is no problem. The purge of the mage robe counters all the damage defying abilities too
