- Arise Crossover Boss Rush now features four difficulty tiers plus the Ultra mode from the Ultra Rush update.
- Each tier drops a unique relic, with the Insane relic granting 57 levels and massive shadow damage.
- Ultra mode costs 50 tickets to enter, so farm tokens through Castle runs first.
- Run 2x Mode Tokens accessories to maximize rewards from every wave.
- New Monarch secret tier gachas pair perfectly with Boss Rush farming.
Boss Rush Mode Overview
The Arise Crossover Boss Rush mode is a wave-based gauntlet where you survive escalating boss encounters to earn relics, titles, XP, and tokens. The Ultra Rush update overhauled the mode by adding an Ultra hard difficulty on top of the existing Easy, Normal, Hard, and Insane tiers, along with four new relics and an exclusive title and accessory for Ultra clears.
Video Highlights:
- Four new relics added, one per difficulty tier
- Ultra mode described as extremely difficult by early testers
- Insane relic grants 57 levels and 805 shadow damage
- Ticket drops inside the mode may not cover the 50-ticket entry refresh
- New gacha Monarch secret tier rolled alongside the update
The core loop is simple: pay an entry cost, clear as many waves as possible, and claim tier-appropriate rewards at the end. Early clears reach around wave 70 with a decent build, but Ultra demands a fully upgraded shadow roster and weapon setup.
| Difficulty | Entry Cost | Key Reward | Notes |
|---|---|---|---|
| Easy | Low | Easy relic | Modest stats, expected for the entry tier |
| Normal | Moderate | Normal relic | Includes options like Ashen Reliquary |
| Hard | Moderate | Shattered Skull | Boosts weapon levels, strong for weapon meta |
| Insane | High | Insane relic | 57 levels, 805 shadow damage |
| Ultra | 50 tickets | Relic + title + accessory | Extremely difficult, newest tier |
Ticket drops inside Boss Rush currently do not reliably offset the 50-ticket refresh cost for Ultra. Do not treat this mode as a self-sustaining ticket farm. Castle runs remain the better token source.
Relic Rewards by Tier
Every Boss Rush difficulty awards a distinct relic, and the jump between tiers is substantial. The Shattered Skull from Hard mode stands out in the current weapon-focused meta, while the Insane relic is a chunky stat stick for shadow builds.
| Relic | Source Tier | Main Benefit | Build Synergy |
|---|---|---|---|
| Easy Relic | Easy | Low stat bonuses | Early progression |
| Ashen Reliquary | Normal | Balanced stats | Mid-game hybrids |
| Shattered Skull | Hard | Weapon level boosts | Weapon meta builds |
| Insane Relic | Insane | 57 levels, 805 shadow damage | Shadow damage builds |
Shadow Builds
- Prioritize Insane relic
- Pairs with Monarch gachas
- Goku edges Halloween Monarch at equal rank
Weapon Builds
- Grab Shattered Skull first
- Current meta is weapons
- Stack weapon level boosts
XP Farmers
- Run Hard for fast clears
- Stack dungeon speed relics
- Add 2x Mode Tokens accessories
If you are switching to the weapon meta, clear Hard mode for Shattered Skull before pushing Insane. The weapon level boost accelerates the rest of your farming more efficiently than raw shadow damage.
Step-by-Step Ultra Rush Progression
Unlock the New Upgraders
Visit Dragon City, Kyama, and Nine to claim the new upgraders. Each has 15 levels, and the gacha roll upgraders let you roll multiple gachas at once.
Farm Mode Tokens via Castle
Castle runs are the most reliable token source. Stack the 2x Mode Tokens accessory to accelerate upgrades and Boss Rush entries.
Roll for Monarch Secrets
Every gacha now has a Monarch secret tier. Use auto roll plus rapid manual taps to speed up rolls and stretch stored gacha charges.
Clear Easy Through Insane
Collect all four tier relics before attempting Ultra. Each relic compounds your stats for the final challenge.
Push Ultra Mode
Enter with a maxed shadow or weapon build. Expect heavy resistance past wave 70 and treat early clears as learning runs.
Following server instability after the update, an XP buff was active. If it returns, use it to push toward the new Adept, Master, and Ascension titles, which grant 60% and 90% buffs at the first two ranks.
Best Loadout for Boss Rush Farming
A single build can serve both XP and drop farming inside Boss Rush. Focus on speed, shared loot, and token multiplication rather than splitting into separate setups.
| Slot | Recommended Pick | Why It Works |
|---|---|---|
| Accessories | XP accessories set | Doubles as drop farming gear |
| Talents | Extra dungeon speed | Faster wave clears |
| Attack | Attack speed + dual wield | Sustains DPS through long waves |
| Loot | Shared loot | Partylevel reward scaling |
| Shadows | Deals with shadows, Vaporal | Boosts shadow damage output |
| Relic slot | Extra relic | Flexible, any strong relic fits |
| Mode bonus | 2x Mode Tokens | Doubles token income per run |
Max rebirth is now 8, and each rebirth adds 25 levels to the cap. Plan your leveling sessions around this extended grind before committing to Ultra attempts.
Ultra Rush Update Extras
Beyond Boss Rush itself, the Ultra Rush update reshaped several progression systems worth tracking:
| Feature | Change | Impact |
|---|---|---|
| Gacha upgraders | Three worlds, single upgrade each | Faster multi-rolls |
| Storms | Drop simple gems | Weapon gem crafting |
| World/Dungeon bosses | Drop 250-400 tokens | Strong AFK token source |
| Rebirth cap | Now 8, +25 levels each | Longer leveling curve |
| Titles | Adept, Master, Ascension | 60%, 90% buffs and beyond |
Ultra Rush Checklist:
- Claim all three new gacha roll upgraders
- Collect relics from Easy through Insane
- Roll at least one Monarch secret gacha
- Reach the Adept title for the 60% buff
- Clear Ultra Boss Rush for the exclusive title and accessory
Castle remains the premier AFK farming spot for tokens and crafting materials. Combine Castle AFK sessions with the new world boss token drops to fund your Ultra entries without active grinding.
Boss Rush FAQ
Q: What is the hardest Arise Crossover Boss Rush difficulty?
Ultra mode, added in the Ultra Rush update, is widely described as extremely difficult. It requires fully upgraded upgraders, high-tier relics from lower difficulties, and a maxed shadow or weapon build to push past wave 70.
Q: Are Boss Rush ticket drops worth the entry cost?
Currently, no. The random ticket drops inside the mode do not reliably match the 50-ticket refresh cost for Ultra. Farm tokens through Castle runs and world boss kills, which drop 250-400 tokens, instead.
Q: Which relic should I get first in Boss Rush?
Clear Hard mode for Shattered Skull if you are running the weapon meta, since its weapon level boosts accelerate all other farming. Shadow builds should target the Insane relic for its 57 levels and 805 shadow damage.
Q: How do the new gacha roll upgraders help Boss Rush?
The gacha upgraders in Dragon City, Kyama, and Nine let you roll multiple gachas simultaneously, making it far faster to chase the new Monarch secret tier and build the shadow roster needed for Ultra clears.
