Mastery Progression

Mastery Progression is the numeric backbone of the system the Mastery & Progression page describes qualitatively: every weapon, magic type and fighting style you use accumulates its own mastery, unlocking new abilities and moves as it climbs. The client's progression formulas document a of 100 and a base of 250 per qualifying action, feeding into a curve with two documented constants: a of 90 and a of 1.025.

Read together, those constants describe a compounding (geometric) requirement curve rather than a flat one- each mastery level costs roughly 2.5% more XP than the one before it, seeded from a base of 90. Over 100 levels that 2.5% compounds substantially, meaning the gap between, say, level 90 and level 100 is far wider in raw XP terms than the gap between level 1 and level 10. The exact function that turns and into a per-level requirement was not extracted (it is referenced only as an internal function in the client data), so this page documents the confirmed constants without asserting the precise output number for any given level.

Mastery gain is also tunable by content type. The mission board's own mastery formulas show a of 30 with a of 5 and an of 10; meaning elite mission-board kills grant meaningfully more mastery progress per kill than normal ones, on top of an of 3 applied elsewhere in the same reward formula. This confirms mastery gain is not just a function of your build's, but also of what you're fighting.

Race choice compounds directly with this curve: Human's Quick Study trait grants a flat +5% Mastery Gain, making it the only documented race that explicitly accelerates the mastery track (see the Human race page). Given how steep the late-game mastery curve is, that 5% has more absolute impact at mastery level 80+ than it does at level 10, since each level demands more XP than the last.
