Heroes & Evolution — every hero's numbers, decoded

The Heroes & Evolution page is the reference counterpart to the Hero Builder. The builder is a planning tool — pick a skin, a level, a weapon, share a link. The new page answers the questions under that: what does this hero actually start with, what do I pay to star them up, and what does evolving them cost? All 24 heroes are there, portraits and all, grouped by rarity — click one, or deep-link straight to it (…/heroes/#h=Assassin for Azio, for example).

What's on the page

Each hero's card has five sections, every number pulled from the game's tables:

Base stats by level — the real ATK/HP anchors from level 1 to 130, plus the level-up cost in Evolution Coins and a total-to-max figure. Heroes of the same tier group share one curve; that's stored in the data, not an approximation.
Level-up milestone perks — the stored bumps at levels 5, 10, 15 … 130: ATK/HP boosts and bonus-option slots.
Star ladder 1★–6★ — Hero Piece cost per star and what each unlocks: skill unlock, equip stat bonus, skill upgrade, hold bonus.
Evolution chain — each step up the rarity ladder with its Evolution Coin + Hero Piece cost, and the cumulative StatReduction ladder.
Lore & skills — the same locale text the rest of the site uses, cleaned of Unity markup.

Here's Azio's evolution, exactly as the tables store it:

Hero	Rarity	Evolution	Cost
Azio	Mythic	→ Exotic	120 Coins + 840 Hero Pieces
Katarina	Epic	→ Legendary → Ancient → Mythic → Exotic	4 steps, 290 Coins + 1,550 Pieces
Freyja	Exotic	—	no evolution rows (already top rarity)

Real numbers from the tables, as stored — open Katarina's page or Azio's page for the full per-step breakdown.

The honest bits

Reverse-engineering means some labels are reconstructions, and we say so on the page. The option-type codes in the milestone and star tables are bare integers in the game files (1, 2, 5, 9, 11, 12) — the page labels them from where they appear (ATK, HP, bonus-option slot …) and always shows the raw value alongside. Skill numbers show X% because the game computes those at runtime; the surrounding effect text is the game's own. And three heroes — Freyja, The Skull and Hana — ship with no evolution rows in v26.0.0: they're already Exotic, so either they're complete or the system arrives for them later.

Why it matters: "how much does evolving cost" is exactly the question that decides whether you push a hero or bench them. Now the answer is one click away, with the game's own numbers — not a wiki guess.

Also in your Discord

The bot got the same data the same day. There's a new /evolution command — /evolution Azio drops the chain, totals and star ladder into chat — and every /hero card now deep-links straight to that hero's section of the page. Same source JSON, so the site and the bot can never disagree.

What's next

The natural follow-ups: a per-hero comparison view (two heroes side by side) and a "what can I afford" check against your current coin and piece balances. And when 26.0.0 ships its Rune tables, the same pipeline that produced this page will produce the rune reference — and the bot's /rune command.
