Fusions and Collaborations
At theSeal Altar two jutsu become one, much stronger.
When it appears
The Altar appears as an event when you have at least two jutsu at level 8 (or, more rarely, any two jutsu to make collaborate). When a level up makes a fusion possible, the game tells you.
Fusing
- Bring two jutsu to level 8.
- Reach the Altar on the minimap and choose the fusion.
- If the pair has a ricetta, a much stronger combined jutsu is born that takes a single slot. If it doesn't, it becomes an Unstable Jutsu.
You discover recipes by trying them. The ones you've found are in the panel Combined panel. Here in Combined jutsu you'll find which ninja can try them alone, and on each ninja's page the fusions of their kit.
Collaborations
At the Altar you can also make collaborare any two jutsu, at any level. They take one slot, both stay active, keep growing and get a random bonus. You can do it 2 times per run at most, and fusions plus collaborations can't go over 3.
An early collaboration frees a slot for a third jutsu. Handy when you have two weak jutsu you don't want to lose.
Past the max level
I Forbidden Scrolls are rare and dropped by generals and legendary enemies. They push a maxed jutsu even higher.
