Two branches per spell
Each of the 408 spells carries two upgrade fields — upgradeA and upgradeB — representing two distinct ways to improve it. The choice is the classic build decision: a straight buff versus a new angle.
Real examples
| Spell | upgradeA | upgradeB |
|---|---|---|
| Ablution (Defense/Water/Common) | Increase base Block gained by 4 | Gain 2 Rain |
| Artery (Attack/Fire/Uncommon) | (stat branch) | (effect branch) |
| Accumulation (Defense/Water/Uncommon) | (stat branch) | (effect branch) |
The pattern holds across the set: A tends to deepen the spell’s main number, B tends to add an effect or secondary resource (Rain, Reinforce, extra triggers).
How to choose
- Pick A when your build already wants more of what the spell does — e.g. a Block-focused Defense core takes Ablution’s +4 Block.
- Pick B when the new effect enables a combo — e.g. Rain or Reinforce that feeds another spell’s trigger.
- Match the branch to your socket plan. A bigger number helps a Countdown spell you cast often; a new effect helps a spell you cast for its side trigger.
Common trap
Don’t auto-take the branch with the larger printed number. A +4 Block is meaningless on a spell you never cast, while a small new effect on a frequently-rolled spell can snowball the whole loadout. Judge the branch by how often the spell fires in your set.
