One staff that I’ve been wanting to see, even before in VT2 would be as follow.
based in VT2 on this spell:
Sanguine Swords - The air around the wizard takes on a fiery glow as up to 6 red swords materialize, floating before him. At a gesture, the swords fly toward a victim and attack, and the target can be switched over time.
Where instead of acting like how Assail work here would work would turn into a heavy gun that work with an ‘ammo mechanic’ and strong projectiles that have to be reloaded, but still work on the Peril (or heat for Sienna).
Summary
Assail Staff, reloading (maybe on special) generate 5-6 shards, light attack will throw a single shard, heavy projectile that will be strong against carapace.
While Heavy will focus all remaining shards, to then throw them all in a volley.
