Zodiac Trials are Anime Zero’s weekly 5-Star boss gauntlet β and the single best source of Zodiac Coins, SSR Choice Shards, and Universal Gems in 2026. The catch: you only get three attempts per week, and the boss’s elemental counter changes every rotation. I’ve cleared every Zodiac Boss since Chapter 6 unlocked the mode, and this guide covers exactly how to play, each boss mechanic you’ll face, the rewards worth prioritizing, and team comps that clear runs without whales. Quick reference before we dive in:
| Quick Facts | Details |
|---|---|
| Unlock | Complete Chapter 6 of the main story |
| Attempts | 3 per week, shared across all bosses |
| Boss | Weekly rotating 5-Star Zodiac Boss |
| Core mechanic | Elemental counters change each week |
| Top rewards | Zodiac Coins, SSR Fragments, Choice Shards, Universal Gems |
Zodiac Trials is a weekly boss mode unlocked after finishing Chapter 6. Each week, a 5-Star Zodiac Boss rotates in with a fixed element, moveset, and gimmick. You get three attempts total, shared across every boss that week β fail all three and you’re locked out until the Monday reset. Two things new players miss: gacha-exclusive and event-exclusive SSRs never appear in the trial pool, and the Zodiac Shop sells SR units built specifically for this mode, so free players stay competitive. If you’re still working through the story, my Anime Zero beginners guide speeds up Chapter 6.
Attempts never refund, so if you wipe twice, stop and re-gear instead of burning your last try.
Every Zodiac Boss fights the same way: the counter element is the fight. Damage counters outperform raw stats β a well-built counter unit beats a stronger off-element DPS every time.
Counters rotate weekly, so re-check the boss preview before committing an attempt.
First clears pay the biggest chunk; repeat wins still drop coins. Here’s the full loot pool:
| Reward | Source / Use |
|---|---|
| Zodiac Coins | Every clear; spend in Zodiac Shop |
| SSR Choice Shards | Shop; pick your own SSR |
| Random SSR Zodiac Trial Fragments | Boss drops; craft trial-exclusive units |
| Universal Gems | Shop; upgrade any unit |
| SR Zodiac Units | Shop; budget counter options |
Coins are the priority currency β I buy SSR Choice Shards first, Universal Gems second. Fragments are the long game: they eventually craft an SSR the gacha can’t give you. Top up free pulls with the latest Anime Zero codes before farming.
The comp that never fails me: two counter-element DPS, one cleanser, one tank. Bosses punish off-element teams, so skip non-counter attackers even if their stats are higher.
After completing Chapter 6 of the main story. The mode then resets every Monday with a new 5-Star Zodiac Boss.
Three per week, shared across all bosses. Failed runs consume an attempt, so test teams carefully.
SSR Choice Shards and Universal Gems from the Zodiac Shop, plus Random SSR Zodiac Trial Fragments that craft trial-exclusive units.
Yes β boss element, moveset, and counter requirements rotate weekly. Always recheck the preview first.
Absolutely. Gacha and event SSRs are excluded from the boss pool, not your team β they’re often your best counters.
