The calculator handles costs. Academy explains Health vs. Lethality, slot priorities, Essence Stones, Mithril, Legendary progression, and why upgrade charts disagree.

Hero Gear Calculator & Upgrade Planner
Pick the troop, slot, and goal you are working on, then calculate the Mythic Gear XP, Essence Stones, and Legendary milestone materials before you spend them. Frost gives you the math and the priority context without pretending one fixed chart fits every account.

1 · What are you upgrading?
High priority
Infantry are your frontline. Gloves and Belt improve the Health side of the set and are the strongest general-purpose Infantry investments.

This section calculates Mythic Enhancement levels 0–100. Legendary gear resets to its own progression after ascension, so its milestone costs are planned separately below.
3 · Mastery Forging
How many Essence Stones?

Mythic Mastery Forging costs 10 Essence Stones for level 1, 20 for level 2, and continues upward through 100 for level 10.

Legendary enhancement XP and post-10 Mastery materials are separate from these empowerment gates. This planner deliberately does not pretend Mithril is the only late-game bottleneck.
Still asking “which one?”
That is an Account Review question.
If several pieces are affordable and you want the best move for your actual heroes, stats, goals, and resource situation, Frost can review the whole account instead of guessing from one gear screen.

Mythic Enhancement uses the level-by-level XP costs through level 100. Mythic Mastery Forging is calculated through level 10. Legendary planning covers the ascension and Mithril empowerment gates at 20/40/60/80/100, including the spare Mythic gear requirement and required Mastery level. Legendary Enhancement XP and post-10 Mastery costs are intentionally kept separate until they can be modeled without muddying the result.
