Effect:

"Slam" "Fully charged attacks knockback and strike all nearby foes."

As says, when its fully charged it has a "Sweep" with bonus knockback (not a ton more, just a little) that hits nearby foes as well.

When you activate this it swirls out a bunch of smoke particles in Montu's colors.

Relabel/reskin of old 'Monthu's Strike" artifact.
