Ninja Time Boss Rush Guide
Boss Rush is the long wave climb used for spin milestones and the Obito / Intangible Eternal quest. AllThingsHow’s September 7, 2026 Intangible guide gates the ultimate behind a Wave 15 Intangible boss with about a 10% spawn chance every 15 waves.
Community reward tables list Mastery XP, XP and Copper every wave, plus Clan / Element / Family spins and Curse Tokens at waves 10, 25, 50, 75 and 100. It is not the same mode as the 30-wave War Mode challenge.
What Boss Rush is
Boss Rush chains elite fights in an endless-style wave format. You push as far as your kit allows for spins and Curse Tokens, or you specifically farm Wave 15 for the Intangible spawn while on “Your New Light”.
Intangible Wave 15 route
Enter Boss Rush, survive early bosses such as Reihaku, reach Wave 15, and reroll runs until Intangible appears (~10%). Kill it, then talk to the Rift Walker near the Uchiha hideout to finish the Obito Eternal chain.
| # | Name | Description |
|---|---|---|
| 1 | Enter Boss Rush | Open Boss Rush from the in-game modes / arena menu. Bring AoE, sustain and food — you need to survive fourteen waves before the Wave 15 check that matters for Intangible. |
| 2 | Clear early bosses (Reihaku and others) | AllThingsHow notes bosses such as Reihaku appear on the way to Wave 15. Treat them as gear checks; dying early wastes the run but does not soft-lock the quest. |
| 3 | Wave 15 Intangible spawn roll | The Intangible boss has about a 10% chance to appear every 15 waves. Most runs will not spawn it — repeat Boss Rush until the red-exclamation objective updates. |
| 4 | Kill Intangible, then talk to Rift Walker | For the Obito / Intangible Eternal chain: defeating the boss flips “Your Eye Compartment became a Light Compartment!” Then talk to the Rift Walker near the Uchiha hideout to finish “Your New Light”. |

| Wave 75 | 5 spins of each type; 3 Curse Tokens |

Boss Rush tips
Dying to Intangible does not void the quest attempt. Bring sustain or Immortal Second Life if you solo. Pair Friday–Sunday 2x XP with post-rebirth Boss Rush sessions.
- Farm Wave 15 specifically when you are on the Intangible Eternal quest — do not reset early for vanity kills.
- Dying to the Intangible boss does not void the attempt; only a kill counts.
- Stack spins from Boss Rush milestones with November codes before Divine / Mythic clan hunts.
- Pair Boss Rush XP with Friday–Sunday 2x XP weekends after a rebirth.
- Bring a second life tool (Immortal Second Life, substitutes) if you solo Wave 15.
Boss Rush FAQ
Quick answers about Wave 15 odds, reward milestones and how Boss Rush differs from War Mode.
- What is Boss Rush in Ninja Time?
- Boss Rush is an endless / long-form wave mode where you fight escalating bosses. It is the required farm for the Intangible (Obito) Eternal ultimate and a strong spin + Curse Token source at milestone waves.
- Why does Wave 15 matter?
- The Intangible boss can spawn at Wave 15 (about 10% chance every 15 waves). Killing it is the combat gate for the “Your New Light” Obito rework quest before the Rift Walker turn-in.
- What rewards does Boss Rush give?
- Community tables list Mastery XP, XP and Copper every wave, plus Clan/Element/Family spins and Curse Tokens at waves 10, 25, 50, 75 and 100.
- Is Boss Rush the same as War Mode?
- No. War Mode is a ~30-wave team challenge with a boss every 10 waves. Boss Rush is the longer wave climb used for Intangible spawns and higher spin milestones.
