Where each piece sits, what level it wants, and what the whole plan actually costs you.
Mithril and Mythic costs are read straight off the Gear Empowerment screen: 10, 20, 30, 40 and 50 Mithril at the five gates, with 3, 5, 5, 10 and 10 Mythic pieces burned alongside. Essence Stones are the Mastery bill each gate demands — Mastery 11 for +20 through Mastery 15 for +100 — totalled on the rule that each Mastery level costs ten more than the one before it. Enhancement XP is left out; the per-level numbers are too loose to add up honestly. Century Games adjust these systems from time to time, so treat every figure here as the shape of the cost rather than a promise — check the screen before you spend.
