2 for shieldgate + armor strip.
3 for forcing rubble gain.
1 for group clear/general damage.
4 mostly dump but can use if wanted.

Avenger synergizes with [Atlas] immunity during 1 + allowing 1 to crit.

Try to upkeep >1400 with 3 + [Path Of Statues] if mostly staying in one place (= enemies will actually be petrified).
