Talent Points are a part of Cyntara that provide offensive, defensive and utility effects. They can be accessed by the top left under Character.
Talents can be gained through completing quest, chest quests, and various activities throughout the game.
Note: If a talent says increases the maximum, it literally means increases the MAXIMUM, not the CURRENT %.
Artifact Talent Points
These are obtained through Minor Artifact Talent Tokens, Major Artifact Talent Tokens, or through killing monsters in 1200+ zones. These will enhance your artifact spells further and generally follow the rule of:
Rank 1: Soul Cost Removal
Rank 2: Duration Increase
Rank 3: Damage Increase/Projectile Increase/Damage Reduction/Healing Increase
