Stasis banks several of the evoker's spells and releases them all at once when reactivated. Stored casts re-fire with whatever bonuses are active at release rather than at the time of banking.

Common bankable spells include Dream Breath, Temporal Anomaly, Reversion, and Emerald Blossom. Stored empower spells also remember the empower level they were cast at, so banking them at full empower preserves that on release.

Cauterizing Flame / Naturalize can also be banked to set up a multi-target dispel: cast the dispel on several different targets back-to-back into Stasis, then release to dispel them all simultaneously.

Assign it as a setup tool for a heavy damage window: bank the relevant spells beforehand, then time the release to land all stored casts at once.

The bank and the release can sit up to 30 seconds apart, so the two healing loads can be assigned to separate damage events if that splits better than one combined dump.

Pair it with the burst window you want amplified rather than treating it as a standalone reactive cooldown.
