Release Notes
Sat May 16 2026
Spell Pages — Full Mastery Breakdown
- Each spell now shows per‑mastery effect text for None / Basic / Advanced / Expert, with placeholders filled from the spell's actual buff data (durations, % modifiers, etc.)
- Spellpower scaling rule surfaced explicitly — e.g. Twilight shows "Duration scales with hero Spellpower: +1 round per 6 Spellpower"
- "Upgrade" section explains exactly what each mastery jump adds (e.g. "Base effect duration: 1 > 2", "Targets deal –15% Melee Damage", "Affects all enemy creatures")
- New Learn Cost (with resource icons) and Upgrade Cost per mastery tier
Cost Rows with Real Resource Icons
- Unit, hero and building costs render as
4,000 🪙 2 💎with real gold/gemstones/wood/ore/crystals/dust/mercury sprites instead of plain text - Each amount carries the localized resource name as a hover/tooltip + screen‑reader label
- Building cost columns benefit too — every level shows the right icons per resource
Hover Tooltips Fixed
- Unit tooltips now show HP, ATK, DEF, DMG, INI, SPD (some were silently missing before because of a property‑name mismatch)
- Upgrades show deltas vs the base unit — e.g. Rift Arbitrator tooltip reads
ATK: 22 (+2), DEF: 24 (+4), INI: 12 (+7), SPD: 5 (+1) <b>/<i>markup that used to render literally as<b>does not</b>is now stripped out- Sub‑skill "Battle bonus:" rows resolve to readable names (Warrior, Campaign, Mage, …) instead of internal
skill_warrior_and_mage_…sids
Hero Page — Specialization Inline
- Specialization name + description now render directly on the hero page (no more clicking through just to read what it does)
{0}/{1}placeholders in the spec description are filled from the spec's bonus params (e.g. Ister now reads "He has +5% Movement points for every 5 hero level(s)…" inline)- "View details →" link remains for the full effects breakdown
Sub‑Skill Pages Show Their Parent
- Each sub‑skill page now shows the parent skill + tier it unlocks at, as a clickable link in the header — e.g. on sub_skill_formation_4 the header now reads
Sub‑Skill · Formation (Expert)
Upgrade Path Icon Fix
- The unit upgrade chain (and other cross‑link cards across the site) sometimes rendered a wrong icon (e.g. Rift Arbitrator showed a Ra'shoth icon). Fixed — every icon now uses the current version hash, so stale sprites can't bleed through
Artifact List — Hand Slots Corrected
- Artifact slot labels for Main Hand and Off Hand were swapped — weapons (swords, bows, staves) were filed under "Off Hand" and shields/secondary items under "Main Hand". Now correctly labeled
Wed May 06 2026
Game Mechanics Page
- New Game Mechanics page with verified info from game files
- Damage formula
DM = (20 + Attack) / (20 + Defense), Luck/Morale ranges (−5 to +5), faction-mix Morale penalty table, retaliation rules, ranged penalties - Stat labels (HP, ATK, DEF, Luck, Morale, etc.) link to the relevant section with hover tooltips explaining the mechanic
Hover Previews Everywhere
- All listing pages (heroes, spells, units, skills, etc.) now show entity previews on hover — no need to open new tabs to compare
- Hero tooltips include: faction, class, starting attributes (ATK/DEF/SP/INT), specialization, starting skills, starting army
- Specialization tooltips show description + bonuses
- Cross-linked entities throughout the site get the same preview treatment
Town Build Trees
- Each faction page now shows the full town build tree at the bottom, laid out exactly like the in-game town view (using the game's
nodePoscoordinates) - SVG arrows connect every prerequisite to its dependent — see at a glance what unlocks what
- Building list now includes 10 previously missing faction-unique buildings (Skeleton Converter, Well of Souls, Mycelium Roots, Rebirth Shrines, etc.)
Skill Synergies ("Compatible With")
- Skill pages now show which other skills double their effects, parsed from in-game descriptions
- Example: Offense lists Luck (via Battle March), Resistance (via Chronic Weakness), and Nightshade Magic (via Shadow Blades)
- Quoted skill names inside descriptions are clickable links to those skills
Skill Page Fixes
- Faction skills (e.g. Righteousness) now show their actual per-level effect text instead of broken placeholder references
- Sub-skill bonus descriptions resolve cleanly — e.g. Strong Mounts now reads "Second Wind mana cost: –4" instead of raw spell IDs
- Many bonus types now render correctly: spell power per school, magic counters, resource gain, summon bonuses, scouting range, mana restore, and more
Unit Page Fixes
- Unit ability and passive descriptions now display (Flying, Ranged Attack, faction-specific abilities, etc.)
- Stat labels link to the mechanics page with tooltips
Themed Scrollbar
- Build tree and other horizontally-scrolling content use a styled scrollbar matching the site theme
