- Best relics in Arise Crossover come from Infernal Castle and Infinite Castle boss floors
- Crystal of the Abyss dropped on Infernal Castle Floor 150 and boosted weapon level by +36 to +75
- Infinite Castle Floor 200 relic grants weapon level, shadow level, and damage stats in one slot
- Relic slots can be expanded by swapping the 3.5 weapon damage talent for +1 relic slot
- Expect multiple clears — Floor 200 relic farming took roughly four attempts in testing
Best Relics Overview: Why They Matter
Relics are the single biggest late-game DPS multiplier in Arise Crossover. While weapons, gems, and skills add incremental power, a freshly upgraded relic can raise a weapon build from roughly 350 NoTG DPS into the 200+ QaG range once titles and multipliers stack. If your damage feels stuck, your relic setup is almost always the bottleneck.
Video Highlights:
- Farming the Floor 150 Infernal Castle relic (Crystal of the Abyss) and upgrading it immediately
- Repeating Infinite Castle Floor 200 until the multi-stat relic dropped after about four tries
- Swapping a 3.5% weapon damage talent for +1 relic slot and resetting stats
- Testing the final build against Boss Rush Ultra and the Floor 400 Infernal Castle target
One strong relic slot often outperforms several smaller bonuses. Prioritize relic quantity first (more slots), then upgrade quality.
Best Relics Tier Rankings
The table below ranks the relic types players are chasing right now, based on which farming locations produce them and the stat packages they deliver.
| Relic | Source | Key Stats | Rating |
|---|---|---|---|
| Infinite Castle Floor 200 relic | Infinite Castle (Floor 200 clear) | Weapon level, shadow level, weapon damage, shadow damage in one slot | ★★★★★ |
| Crystal of the Abyss | Infernal Castle (Floor 150 boss) | Weapon level scaling up to +75 when upgraded | ★★★★★ |
| Boss Rush relic | Boss Rush (Ultra mode reward) | Strong combat stats, gated behind Ultra clear difficulty | ★★★★ |
| Floor 350+ Infernal relics | Infernal Castle high floors | Higher baseline weapon level than Floor 150 drops | ★★★★ |
| Standard weapon level relics | Early Infernal Castle floors | Flat weapon level bonuses, replaced quickly | ★★★ |
The Infinite Castle Floor 200 relic does not drop every clear. In testing it took about four full clears (20 waves each, with several minutes of waiting per attempt) before the relic finally appeared.
Relic Farming Locations Compared
Infernal Castle
- Spawns periodically on the map
- Start from Floor 140-150 checkpoints
- Floors 150-400 have relic-dropping bosses
- Great for cash and gems alongside relics
Infinite Castle
- Fixed 20-wave format per attempt
- Floor 200 clear gives the multi-stat relic
- Long wait between waves (~7 minutes in tests)
- Must repeat full runs on failed drops
Boss Rush
- Ultra mode drops a dedicated relic
- Bosses have very high health pools
- Only attempt after two strong relics are equipped
- Best saved for last in your farming rotation
| Location | Time per Attempt | Relic Drop Chance | Best For |
|---|---|---|---|
| Infernal Castle (Floor 150) | Fast with checkpoints | Decent (first-try in testing) | Early relic + currency |
| Infinite Castle (Floor 200) | 20 waves, slow waves | Low (took ~4 tries) | Endgame multi-stat relic |
| Boss Rush Ultra | Moderate | Reward-based | Post-relic power spike |
Your displayed DPS may be total across all NPCs hit rather than single-target. If a build feels weak on paper, test it on a single high-health boss before switching setups.
Step-by-Step: Building a Relic-Focused Weapon Build
Farm Infernal Castle Floor 150
Wait for Infernal Castle to spawn, enter the checkpoint, and clear to the Floor 150 boss. Kill it for the Crystal of the Abyss and collect cash and gems along the way.
Upgrade Immediately
Head to the upgrade menu right after the drop. Crystal of the Abyss scaled from +36 weapon level at base toward +75 with investment — never let a new relic sit un-upgraded.
Repeat Infinite Castle Floor 200
Clear the 20-wave run repeatedly until the multi-stat relic drops. Bring weapon potions and expect several attempts; wave 199-200 is where the reward lands.
Reset Stats for More Relic Slots
Use a stat reset and replace the 3.5 weapon damage talent (Weapon Transcendence 3) with +1 relic slot. Two strong relics beat one talent at this stage.
Stack Multipliers and Test
Equip a weapon damage title, runed weapons with gems, and a weapon potion, then test DPS. Only after this stack should you attempt Boss Rush Ultra.
| Build Element | Slot | Priority |
|---|---|---|
| Two runed weapons | Weapon slots | High |
| Crystal of the Abyss | Relic slot 1 | High |
| Infinite Castle relic | Relic slot 2 | High |
| Weapon damage title | Title slot | Medium |
| Weapon potion | Consumable | Use for boss attempts |
After stacking two upgraded relics, a title, and the +1 relic slot swap, DPS jumped from roughly 5 NoTG to the 20+ UQ range — enough to seriously challenge Ultra mode bosses.
Optimization Tips & Common Mistakes
- Speed multipliers favor shadows, not weapons. Four-times speed appeared to accelerate shadow builds but showed no effect on weapon attack speed — don't waste the setting expecting weapon gains.
- Consider disabling AoE attacks on crowded floors if single-target DPS on bosses is your goal; spread damage inflates your DPS readout.
- Subtitles vs. relic slots: the "equipped title + subtitle" combo can compete with an extra relic slot. Test both in the training scenario before spending a reset.
- Don't chase Floor 400 early. The video's author couldn't clear Floor 400 before stacking two top relics — treat it as a post-Ultra goal.
Swapping relics without a stat reset wastes slot potential. Always reset first, then rebuild around your maximum number of usable relic slots.
Relic Progression Milestones:
- Clear Infernal Castle Floor 150 and obtain Crystal of the Abyss
- Fully upgrade your first relic
- Clear Infinite Castle Floor 200 until the multi-stat relic drops
- Reset stats and equip +1 relic slot instead of Weapon Transcendence 3
- Attempt Boss Rush Ultra with the full relic stack
FAQ
Q: What are the best relics in Arise Crossover right now?
The Infinite Castle Floor 200 relic and Crystal of the Abyss from Infernal Castle Floor 150 are the top picks. The Floor 200 relic bundles weapon level, shadow level, and both damage types into one slot, while Crystal of the Abyss scales weapon level up to around +75 when upgraded.
Q: How long does the Infinite Castle Floor 200 relic take to farm?
Each attempt is a 20-wave run with slow late waves — around 7 minutes of waiting near wave 199. Drop rate is inconsistent; in testing it took roughly four full clears before the relic appeared.
Q: Should I take +1 relic slot or the 3.5 weapon damage talent?
Once you own at least two strong relics, the +1 relic slot generally wins because each upgraded relic contributes far more than 3.5% weapon damage. Use a stat reset to make the swap cleanly.
Q: Why does my weapon DPS feel lower than displayed?
Your DPS readout may reflect total damage spread across every NPC hit rather than single-target damage. Test on one high-health boss, and remember speed multipliers boost shadow builds but not weapon attack speed.
