Need Advice About Hexblast of Contradiction

hi, i find this amazing attribute stack bosskillah build,

this is my try: https://pobb.in/0kvrGkZ5zCJL


there is a way to make maps viable without distorting the build?
i try to switch hexblast gem with firestorm of meteors but is not so great....
i don't pretend a zoom zoom variation but only can reach boss without switch char with some more aoe....
minefield gem? volatile mine on tree? explode on kill flask?

ty in advance for answers

p.s. now i switch hexblast with cracking lance of contradiction and it seems to be fine for map run!

You can use Awakened blasphemy setup. Just check captain lance video

lose a lot of dps with that setup cos i must to drop wrath (or i need a 80% multiplier helmet + efficiency mana on jewels)
