What Are Relics?

Relics are gear pieces that boost your units' stats. Similar to Epic 7's gear system, relics have main stats and substats. Equipping the right relics can dramatically increase your unit's effectiveness.

Substat Upgrade Strategy

When you enhance a relic, upgrades either improve existing substats (Perk Upgrade) or unlock new ones. Prioritize relics with 5 substats already to maximize value.

5
substats

UPGRADE

All upgrades go into existing stats (Perk Upgrade). Maximum value potential.

4
substats

CONSIDER

Good if main stat is perfect. 1 upgrade might unlock new stat.

substats

AVOID

Upgrades may waste rolls unlocking new substats instead of improving existing ones.

Relic Farming Tips

  • Story Nightmare

    Canonical drop notes describe Nightmare as a high-chance Mythic relic route; exact current rates still need in-game verification.

  • Legend / Higher Difficulty Runs

    Use higher difficulty routes when your team can clear them consistently; exact drop-rate math should be checked against current run logs.

  • Virtual Realm Shop

    Canonical reward notes include relic-related shop items such as Scarlet Maid Plushie and stat reroll resources.

  • Gold Budget

    Upgrade promising relics first; exact gold-to-max values are treated as guide-model notes until verified.

Common Mistakes

  • Stacking Crit Rate on Cyborg

    Crit Rate is multiplicative. +37.5% only turns 15% base into ~20%, not 52.5%.

  • Upgrading weak 3-substat relics

    Usually poor value compared with waiting for stronger Mythic pieces, especially when the main stat is not useful.

  • No sorting feature

    Game lacks sorting. Be careful not to accidentally fodder good relics.
