hello,

never play templar and was a long time i want to do something with fiereball so, i take this build :
https://www.pathofexile.com/forum/view-thread/2687717
from https://www.pathofexile.com/account/view-profile/Arcinde

and try to do something, this pob: https://pastebin.com/vHBgyBPd

the only thing is not correct in, is the node prodigical perfection, so just take the oil recipe for it, and have 3 point free in this tree.

have put random rare item just for cap res and have a bite life/mana, but only put middle tiers.

about unique, i want 3 thing, the staff, an essence worm and a infernal mantle, so 2/3 is easy to have i mean .

what are you thinking about this buid ?

ps: about mechanic, fireball for map clean, fireball+totem (debuff+proc) and flame surge for bosses.
