Character Levels:
Increase a character's base stats (HP, ATK, DEF). Max level is 90. Requires Character EXP Materials and Mora. At certain levels (20, 40, 50, 60, 70, 80), you must Ascend the character using specific regional boss materials and local specialties to raise their level cap.
Talents:
These are a character's Normal Attack, Elemental Skill, and Elemental Burst. Leveling them up increases their damage or effectiveness. Requires Talent Books (farmed from Domains of Mastery), Common Enemy Drops, and Weekly Boss Materials. Prioritize leveling the talents most relevant to the character's role (e.g., Main DPS: Normal Attack, Skill, Burst; Support: Skill, Burst).
Constellations:
Each character has 6 constellations, unlocked by acquiring duplicates of that character. Constellations provide powerful passive buffs, new abilities, or enhance existing ones. While 5-star constellations are often expensive, 4-star constellations can significantly boost a character's power.
