Features:
- Clan & Evolution System: Adds a progression-based clan mechanic. Join legendary lineages to unlock unique stat bonuses, passive abilities, and specialized evolution paths (e.g., Destroyer vs. Guardian paths).
- Binding Vows: Establish powerful self-imposed restrictions to gain massive strategic advantages. Features a radial management menu and built-in punishments for breaking your word.
- Soul & Dialogue System: Absorb the souls of fallen legends to gain permanent passive buffs. Souls feature a "Dialogue System" that reacts to combat, biomes, and world events with custom "blip" audio.
- Custom Technique Builder: An advanced interface allowing players and server owners to forge their own Cursed Orbs by combining skill IDs, custom costs, and cooldowns into a single playable technique.
- Trait & Physiology System: Introduces Physical and Mental traits (like "Vessel" or "Angel") that fundamentally alter your character’s attributes, energy regeneration, and combat speed.
- Systemic Powerhouse: Includes the "All For One" (theft and management) and "One For All" (stockpiled power chains) systems, along with a Global Modifier API for balancing damage, RCT efficiency, and more.
- Tabular UI Integration: Fully utilizes the Tabular Creative API to organize its massive library of techniques, clans, and souls into clean, navigable sub-categories.
