I instead maxed out Fireballing, and that was far and away more powerful, especially once you unlock the Helietrope sign. A few quick blasts, Heliotrope, at which point you could easily generate enough vigor to cast enough signs to put Heliotrope back up indefinitely -- constant Time Slow + unlimited Fireballs at ~+75 damage.
