Rumbling Sky
For a while, lightning strikes foes near you at random. It works around the Mage himself, so it needs no target. Every foe it hits takes 1 shock stack: each stack makes it take 10% more damage from every source. Stacks last 4 s from the latest hit, 3 at most.
A level-up offers it as one of three cards.
Rank by rank
A level-up card offers a skill you do not have while one of your 6 slots is free, or the next rank of one you have, up to rank 5. These are the lines the card shows:
- Rank 1: A bolt of 14 damage every 0.4 s for 3 s within 4.5 tiles, 1 shock stack · 12.0 s cooldown (7.2 s with Quick Hands at rank 5)
- Rank 2: A bolt of 17 damage every 0.4 s for 3.5 s within 4.75 tiles, 1 shock stack · 11.5 s cooldown (6.9 s with Quick Hands at rank 5)
- Rank 3: A bolt of 21 damage every 0.4 s for 4 s within 5 tiles, 1 shock stack · 11.0 s cooldown (6.6 s with Quick Hands at rank 5)
- Rank 4: A bolt of 26 damage every 0.4 s for 4.5 s within 5.25 tiles, 1 shock stack · 10.5 s cooldown (6.3 s with Quick Hands at rank 5)
- Rank 5: A bolt of 32 damage every 0.4 s for 5 s within 5.5 tiles, 1 shock stack · 10.0 s cooldown (6 s with Quick Hands at rank 5)
| Rank | Cooldown (s) | Damage | Reach (tiles) | Lasts (s) |
|---|---|---|---|---|
| 1 | 12 | 14 | 4.5 | 3 |
| 2 | 11.5 | 17 | 4.75 | 3.5 |
| 3 | 11 | 21 | 5 | 4 |
| 4 | 10.5 | 26 | 5.25 | 4.5 |

Evolution: Tempest Sky
Rank 5 + Quick Hands → Tempest Sky. Hold Rumbling Sky at rank 5 and any rank of Quick Hands, and the next level-up’s first card is the evolution, drawn in gold. The storm lasts longer, reaches farther, and each bolt shocks twice as deep.
- Change from rank 5
- +25% damage, +20% area, +30% duration, -10% cooldown
- Damage
- 32 → 40
- Cooldown
- 10 s → 9 s
- With Quick Hands 5
- 5.4 s
Quick Hands is also the key to Ember Dart and Static Brand, so one passive can open three evolutions.
