Soul Badges are a separate advanced badge line with their own progression curve and visual glow effects.

Awakening System

All 6 heroes can Awaken into ultimate classes with new combat mechanics and skills. Each Awakened class plays differently.

Endless Defense

Tower-defense style wave combat. Build-craft with the affix system. Each hero has a dedicated defense talent tree.

Paragon Talents

Endgame progression system unlocked after all heroes are Awakened. Hexagonal talent board with a shared talent point pool.

Artifact System

12 Zodiac constellation artifacts, each with unique combat effects. They drop naturally over time and are displayed in your Artifact Cabinet.

Auto Challenge

Builds & Synergies

Awakened classes, cards, defense affixes, talents, and artifacts can combine in interesting ways. For example:

  • Awakened Archer with talents and the Sagittarius artifact, multi-shot melting enemies

  • Awakened Priest with passives and Paragon talents to wipe the entire screen

  • Awakened Guardian stacking reflect and shields — the more enemies hit you, the stronger you get

  • Awakened Warrior burning HP with lifesteal, getting deadlier the closer to death

  • Awakened Dancer stacking evasion to 100% for permanent invincibility, grouping enemies and detonating them all at once

Different build paths lead to different combat experiences — worth experimenting with.
