You might wanna try lightning strike/frostblades + vaal glacial hammer + multistrike for singletarget. If lightning strike/frost blades projectiles hit a vall galcial hammers/frost walls wall it can chain to enemies nearby. Iirc if you also take the chain gem, after chaining to the boss they will chain in a random direction and chain from the wall to the boss again.

In that case it would be better to use Frost Wall, not a vaal skill. FW can be done regardless of souls, and too many boss fights have adds that don't give you vaal souls.
