Talents are the third prong of Tyranny 's character system. Instead of linear, vertical advancement, talents expand characters horizontally, refining their abilities in a particular field.
Every character has access to talents uniquely suited to them. The Young Fatebinder you play as has six separate talent trees. Companions have two unique trees (three for Sirin and Lantry).
Every time a character gains a character level, they also gain a talent point, allowing one talent to be unlocked. Sirin is unique in that the talents in her Song tree are unlocked automatically by character levels.
All Companions will eventually complete their talent trees; as they have too many choices, the Fatebinder must be more careful in choosing talents as talent choices cannot be undone once confirmed.
