Best Way to Farm Aura Crates
Aura Crates drop at near-lottery odds from normal enemies, so direct farming is only viable during a double-luck event or with the luck gamepass. For every other player, the Infinity Tower shop is the dominant route.
Infinity Tower Shop (recommended)
One Aura Crate costs 1,200 Tower Tokens. A standard overnight AFK session in Infinity Tower earns roughly 20,000 Tower Tokens, which trades into about 16 Aura Crates per night — plus a large pile of Clan Rerolls, Race Rerolls, and occasional Passive Shards as side drops.
Build setup before you AFK
Damage — you need enough to one-shot through floor 50:
- 600–700% total damage clears floor 50 reliably.
- 640% still reaches floor 35–45 — acceptable for slower runs.
- Best sword: Ice Queen (highest total damage in the game).
- Best AFK melee: Strongest Shinobi; Gilgamesh if you don't have it.
Luck — doesn't affect Tower Token income directly, but multiplies side-drops (Clan Rerolls, Race Rerolls) that you'll also want:
- Ascensions (Sailor Island Ascension NPC): up to +30% luck at final tier.
- Infinity Tower skill tree: +30% luck when maxed.
- Boss Rush skill tree: extra luck tier — commonly skipped, worth grinding here.
- Judgement Island spec passive "Fortune": +3% luck.
- Eminence clan + Fortune buff: multiplicative — biggest single boost when rolled.
- Luck gamepass: +100% luck applied on top.
Stacking these reaches 500%+ total luck, which translates to roughly one clan-drop per floor — about 150 Clan Rerolls per 50-floor run.
AFK settings
- Open Infinity Tower settings and set Auto Tower Reset to floor 50 (or 55 if your damage can push it).
- Enable Pay for Replay so the next run auto-starts.
- Instead of waiting ~3 minutes for the run to end naturally, die 5–6 times on the final floor — the run resets instantly.
Alt accounts don't share tower state. A second alt farming its own Infinity Tower effectively doubles your crate output per night.
Alternative: Shinjuku Island AFK
Standing in the air above Shinjuku Island and spamming a ground-targeted skill (Quake is the usual pick) used to be the meta. It's now only competitive when a double-luck event is running or if you have the double-luck gamepass. Without those buffs, skip it and run Infinity Tower.
What Aura Crates open into
Opening an Aura Crate rolls a random aura from the full pool, with rarity weighted toward Common. The best-case roll is a Legendary aura worth +15% damage. Entire aura list is in the Auras & Cosmetics page.
