Supercent's community team posted the full 26.0.0 sneak peek on the official XP Hero Discord, alongside a before/after gameplay short. We've summarized every confirmed detail below — and then went one step further: we swept our entire extraction of the current build (v25.3.0) to see what the game's own files say about what's coming. Short version: both systems ship entirely new, and we can prove it.
Left to right: the Mimic and Treasure Mimic already in our bestiary — likely the
Tomb's "Mimic Room" namesakes — and magic_runecircle, the only
"rune" art in the current build (it's a skill effect, not the new system).
Watch the before/after
▶ How Hero Runes ACTUALLY Upgrade Skills! (Before & After) Official XP Hero short — same skill, different level. Equipping a Hero's dedicated Rune makes the effect stronger and visibly flashier.Tomb of Heroes — the dungeon
A dungeon where shadows of legendary heroes gather. The announcement confirms:
- You pick your difficulty going in. Difficulty sets both the enemies and the item pool — harder runs, better loot table.
- Clear the stages, take down the final boss, dungeon's done.
- Loot only locks in once you finish the run. No early bail with drops in hand — the run has to be completed for rewards to stick.
- Event rooms appear along the way: a Sanctuary to patch up HP, and a Mimic Room if you want an extra fight (and, presumably, extra loot).
- Unlocks at Chapter 2.

| Treasure Mimic | A predator disguised as a forgotten treasure chest. The older it grows, the more convincing its disguise becomes. |
Runes — new gear that upgrades skills
Runes are new equipment that equips like a weapon, in two flavors:
- Normal Runes — flat stat boosts; the stat depends on the rune's type.
- Hero Runes — tied to a specific Hero's unique skill. Equip it on the right Hero and it either buffs that skill or triggers an extra effect. The official short shows the same skill before and after: stronger numbers and much flashier visuals.
Progression: dismantle the Runes you don't need into Rune Powder, then spend Powder plus other materials to upgrade the ones you're keeping. A dismantle-and-reinvest loop — familiar territory for anyone who's been through Weapon Craft.
What the current build tells us
Features often ship dormant — tables and strings parked in the files long before the switch flips. So we swept our full extraction of v25.3.0 at every layer:
magic_runecircle FXThe raw-file sweep covered all 8,344 Unity data files, byte by byte. The only
"rune" the current build contains is magic_runecircle — a magic-circle
skill effect that predates this system entirely.
We checked the Tomb's keywords too, because honest data work means reporting the near-misses: strings for Tomb, Sanctuary and Mimic do exist in v25.3.0 — but they're red herrings. "Lost Sanctuary" is Chapter 1's name, and the Mimics are existing field monsters. (The raw "tomb" hits were mostly the French word tombé.)
Conclusion: there is no dormant rune data. The entire system — tables, locale strings, art, the Rune Powder currency — arrives with 26.0.0. That also means the current build can't tell us costs or numbers; anyone claiming specific rune stats today is guessing.
When it drops, we're ready
The day 26.0.0 lands, the pipeline runs: extract the new APK's data files, and the site updates itself — every number on every page is regenerated from the game's own tables. This post gets updated with the real rune tables: names, types, levels, costs, and which Heroes they belong to.
What we're watching for in the new files:
- New data tables — something like
RuneData/RuneLevelData(the game's table naming is consistent). - New locale keys —
RUNE_NAME_*,RUNE_DESC_*, and the Tomb's room/boss names. - A new currency — Rune Powder should appear in the item table next to Gold, Gems and the orb family.
- Dungeon tables — difficulty tiers, stage waves, and the Tomb's item pool.
Until then: level up, stockpile your dismantling candidates, and get ready to read the actual numbers here first.
