Risen Vaal Fanatic spectre (phys mortar) PoE 3.24

Today i decided to revisit these spectres and to see how they perform with full phys to cold conversion in a proper minion helmet, and well... as you can see in this video they are really good at clearing, but boss dmg is bad. This is with awakened GMP, i tried with greater Volley, but no matter what, they'r mortar spell shoots projectiles in random locations so you can't control the spread.

These look the best out of all the ones you have shown so far this league!
