This reference covers eleven named masteries described for Titan Quest and its expansions: Defense, Dream, Earth, Hunting, Nature, Neidan, Rogue, Rune, Spirit, Storm, and Warfare. The descriptions focus on the recorded damage types, defensive or support effects, summons, and combat functions associated with each tree. The base mastery system lets players spend skill points to access and improve skills, and combine two masteries to form a class. The available passages do not provide individual skill names, exact point costs, acquisition locations, or a comparative ranking. Dream, Rune, and Neidan are identified as additions from Immortal Throne, Ragnarök, and Eternal Embers respectively.
Do not treat Titan Quest 2 descriptions as confirmed sequel mechanics
The mastery page is headed Titan Quest 2 and explicitly says the predecessor masteries may or may not carry over. These records use only its descriptions labeled as Titan Quest predecessor masteries.
Keep expansion-linked masteries in their expansion context
The source identifies Dream as added through Immortal Throne, Rune through Ragnarök, and Neidan through Eternal Embers. The Steam description confirms Anniversary Edition combines the base game and Immortal Throne; the supplied passages do not establish ownership or availability of the later DLCs for a particular player.
Do not infer exact skill costs or effect magnitudes
The passages describe broad mastery functions and the basic skill-point system, but do not provide individual skill costs, numeric effect values, or a detailed allocation path.
A source-bounded reference to eleven named masteries and their described combat functions. Source s1 establishes the original mastery system: after the first level-up, players can spend skill points in mastery trees and combine two masteries. Source s2 describes the eight original masteries and three DLC-added masteries, but does not give individual skill names, exact costs, or detailed progression requirements.
Steam metadata establishes the Anniversary Edition identity and says the edition combines Titan Quest with Immortal Throne; it does not establish mastery mechanics.
Mastery effects are broad descriptions from a page about Titan Quest 2 that separately labels the listed trees as Titan Quest predecessor masteries and cautions they may or may not carry over to the sequel.
No inspected passage supplies individual skill names, exact point costs, effect magnitudes, unlock locations, or comparative performance evidence.
Later expansion mastery availability for a specific Anniversary Edition installation or DLC entitlement is not verified by these passages.
