Cast Changes
- Modifies Storm Of Ukko with: Storm of Ukko Augment: Wrathful Advance moves the storm of daggers to the teleportation location and increases its duration by 6s.
- Rank up the augment to unlock the full effect values.
- Costs a mod slot (and capacity) — only equip it when the change matters for your loop.

- Worth it when the augment’s change is central to how you play Kullervo.
- Skip it if the base Storm Of Ukko already does what you need and you’d rather keep the slot for survivability or strength.
