At theSeal Altar two jutsu at level 8 fuse into a stronger one that takes a single slot. Pairs without a recipe become an Unstable Jutsu.

Recipes (36)

Who can fuse them alone: Naruto 6 Sasuke 6 Sakura 6

Collaboration Technique

At the Altar you can also unire any two jutsu, at any level and without a recipe. They take one slot, both stay active and keep growing, with a random bonus. You can do it 2 times per run at most, and collaborations plus fusions can't go over 3. Joined jutsu can't be fused anymore.

Forbidden Scrolls and Sage Strike

• Forbidden Scrolls: rare, they drop from generals and legendary enemies. They take a maxed jutsu to Lv 6+ (+25% damage, +1 projectile) and then Lv 7+ (another +25% damage, -15% cooldown, +10% area).
• Sage Strike. Every crit has a 3% chance to become a Sage Strike, with ×4 damage and a shockwave on nearby enemies.
