Olden Era Patch 12 Changes Explained
Heroes of Might & Magic: Olden Era received two updates in the space of four days in July 2026, and together they reshape the Early Access meta. Patch 11 (v0.80.31, July 6) was the largest balance pass since the April 30 launch — a full Necromancy rework, sweeping creature and spell tuning, and four new tournament templates. Patch 12 (v0.80.34, July 10) is a smaller follow-up that fixes crashes introduced by Patch 11, buffs Sorcery, and corrects an Arena Mode overcorrection. This guide walks through every change that matters, with the exact before-and-after numbers, and closes with what it all means for your next match.
If you only read one section, read the Necromancy breakdown — the rework changes how every Necropolis game plays out, and the new energy math is easy to misread as a straight buff when it is anything but.
July 2026 Updates at a Glance
| Update | Version | Release Date | Focus |
|---|---|---|---|
| Patch 11 | v0.80.31 | July 6, 2026 | Necromancy rework, faction & skill balance, four new tournament templates, matchmaking overhaul |
| Hotfix | v0.80.33 | July 6, 2026 | Advanced Battle Magic behavior fix, save-loading fix, Summon Avatar description correction |
| Patch 12 | v0.80.34 | July 10, 2026 | Crash and timer fixes, Sorcery buff, Arena draft correction, template tuning |
Patch 12 (v0.80.34) — Every Balance Change
Patch 12 is deliberately small: it exists to stabilize what Patch 11 shipped. Even so, two of its six balance items matter for ranked play — the Sorcery buff is a real power increase for mage builds, and the Arena draft correction changes how the mode's economy feels from the first pick.
| Area | Before | After | Why It Matters |
|---|---|---|---|
| Skill — Sorcery | +10/20/30% magic damage | +20/30/40% magic damage | Direct-damage mage builds get a straight buff at every tier of the skill. |
| Sorcery hero specialties | 10% + 1% per hero level | 15% + 5% per 3 hero levels | Specialists scale far harder into the mid game — a level-12 specialist jumps from +22% to +35%. |
| Arena Mode draft | Larger starting armies from Patch 11 | Draft-phase unit counts reduced again | Patch 11's bigger drafts squeezed magic heroes too hard; this walks the correction back. |
| Template — Sprint | Stables could still appear | Stables fully blocked from generating | No more free movement snowball on the fast Sprint template. |
| Template — Jebus Tournament | Larger starting areas, tougher guards | Smaller starting areas, slightly weaker standard and gate guards | Faster openings and earlier contact on the new competitive template. |
| Template — Helltide | Point of Balance could spawn in side areas | Point of Balance removed from side areas | Less free stat swing from lucky side-area generation. |
The bug-fix side of Patch 12 is short but high value for competitive players: a crash when a player's starting hero was missing at the start of a Jebus Tournament battle is gone, the Heroic Strike hotkey works again, the match timer no longer keeps running for both players while simultaneous turns are stopped, an enemy hero striking under Mirage no longer crashes the game, and an opponent leaving Arena Mode mid-targeting no longer crashes your client either.
Sorcery Spotlight — the Numbers Behind the Buff
Sorcery was a niche pick before July. At +10/20/30% magic damage it lost skill-slot value to almost every alternative, and its hero specialties scaled at a flat 1% per level, which fell behind Might scaling by the mid game. Patch 12 doubles the early value and changes the specialist curve entirely.
- Basic Sorcery now grants +20% magic damage — the old Advanced value, one tier earlier.
- Expert Sorcery grants +40%, a third more than the old cap of +30%.
- A Sorcery specialist at level 6 goes from +16% to +25% magic damage; at level 12, from +22% to +35%; at level 18, from +28% to +45%.
- The trade-off: pure per-level grinding matters less, and milestone levels (every third) are where your power spikes — plan fights around hitting level 9, 12, and 15 before key engagements.
Combined with Patch 11's cheaper Stone Fangs (18 → 11 mana) and Anti-Magic (16 → 12), Primal-flavored damage mages come out of the July updates as the clearest winners in the skill economy. Check the skills overview and spell reference for how the pieces fit into a full build.
Patch 11 Deep Dive — the Necromancy Rework
The headline change of the July cycle is the rebuilt Necromancy. The old system only let you raise a tier of undead if your army already contained that tier, which forced awkward army composition choices. The new system removes that restriction entirely: after any victory, every fallen enemy stack can be raised as the undead of its tier — tier-1 enemies become Skeletons, tier-2 become Wights, and so on up the ladder. If your army does field undead of the matching tier, the raised type follows what you carry: the base version if you field the base creature, the upgraded version (at a higher energy cost) if you only field the upgrade, and the numerically larger stack decides when you field several upgrades. Map tooltips now tell you exactly what a guard stack will raise into before you commit to the fight, and the battle results window lets you cancel the raise and manually recycle corpses into Necromantic Energy instead.
The catch is in the energy math. Maximum energy pools roughly tripled — from 1,000/1,250/1,500 at Basic, Advanced, and Expert to 3,000/4,000/5,000 — but the cost of every single raise went up by a factor of four (3.75 at tier 8). Fewer raises per pool, far more freedom in what those raises can be.
| Tier | Raised As | Old Energy Cost | New Cost (Base) | New Cost (Upgraded) |
|---|---|---|---|---|
| Tier 1 | Skeleton line | 5 | 20 | 26 |
| Tier 2 | Wight line | 10 | 40 | 54 |
| Tier 3 | Matching tier-3 undead | 25 | 100 | 140 |
| Tier 4 | Matching tier-4 undead | 50 | 200 | 290 |
| Tier 5 | Matching tier-5 undead | 100 | 400 | 600 |
| Tier 6 | Matching tier-6 undead | 200 | 800 | 1,280 |
| Tier 7 | Matching tier-7 undead | 500 | 2,000 | 3,500 |
| Tier 8 | Matching tier-8 undead | 2,000 | 7,500 | — |

If you play Necropolis, your week-one plan barely changes — skeleton raises are still cheap relative to income — but mid-game decisions flip: hoarding energy for a tier-7 raise now costs 2,000 energy instead of 500, so recycling low-value corpses into energy becomes a real choice rather than an afterthought. Our Necropolis build guide and Necropolis faction page cover the faction's broader game plan.
Battle Magic & Summon Avatar — the Mage Rebalance
Patch 11 walked Battle Magic back to its original scaling after earlier nerfs to Might heroes pushed mages too far ahead: creature Attack and Defense scaling from Spell Power and Knowledge drops from 15/25/35% to 15/20/25%, and the two Authority sub-skills fall from 20% to 15% each. Elsewhere in the skill trees, Luck now grants an 8% Lucky Hit chance per point (up from 6%), Rhythmic Cadence raises the mana cap bonus to 40% (from 30%), and Stargazer doubles daily Astrology Points from 250 to 500.
Summon Avatar was reworked into a build-around rather than a default pick. The summon now survives exactly 3 hits at every skill level, its base damage falls to 10-10, Spell Power scaling drops to 6/8/10 per point, and as a Tier-4 spell it carries a 5-round cooldown. The compensation is real: Avatar of Fury adds +40% damage, Avatar of Celerity adds +2 Speed and Initiative, and the new Summon Destruction sub-skill gives your hero and army +50% damage against summoned creatures. Slotting Effortless Strike and Ancient Scrolls now requires Expert-level parent skills, while Swordcraft and Thaumaturge Brilliance moved down to Advanced — check your saved builds before queueing into ranked.
Creature Balance — Winners and Losers
Patch 11 touched almost every roster. These are the changes with real game impact; faction pages for Grove, Dungeon, and the rest are being updated to match.
| Faction | Unit | Change | Impact |
|---|---|---|---|
| Necropolis | Dread Knight | HP 100 → 80 | Tier-6 anchor gets noticeably frailer. |
| Necropolis | Avatar of War | HP 100 → 80, Initiative 11 → 10 | Slower and squishier. |
| Necropolis | Hollow Reaper | HP 100 → 80, Damage 22-24 → 24-26, Initiative 10 → 11 | Trades bulk for speed and damage. |
| Necropolis | Lich & Sanguine Lich | Damage 12-16 → 13-16 | Small damage bump for the caster stack. |
| Necropolis | Pestilent Lich | Attack 16 → 12 | Pushes the upgrade toward its support role. |
| Necropolis | Wraith | Phantom Vampirism healing 40% → 30% | Less self-sustain on the tier-2 line. |
| Necropolis | Vampires (tier 7) | Vampirism healing 40% → 50% | Top-end lifesteal gets stronger. |
| Necropolis | Tier 2 / Tier 3 dwellings | Weekly growth 16 → 19 / 13 → 14 | Faster early and mid-game army build-up. |
| Grove | Hoplet line | Damage 3-6 → 4-8, Attack and Defense up on all variants | Tier-2 fights stop being a liability. |
| Grove | Phoenix line | Speed 7 → 8 (base), 9 → 10 (upgrades); stat bumps | Phoenixes reach key targets a step earlier. |
| Dungeon | Black & Ashen Dragon | Damage 60-65 → 65-75 | Big buff, on top of the alt-attack damage fix. |
| Dungeon | Cave Dragon | Damage 45-50 → 50-60 | Base dragon hits much harder. |
| Dungeon | Hydra line | Initiative 8 → 6 (Infernal 10 → 8), Chthonic Defense 34 → 30 | Slower, easier to focus down. |
| Temple | Griffin line | HP 25 → 30 | Tier-3 dive bomb survives the return hit more often. |
| Temple | Crossbowman line | Initiative 5 → 4 (Marksmen 7 → 6) | Ranged opener acts later in round one. |
| Hive | Waurms / Devourer / Pyroboros | Attack & Defense 20 → 21; Devourer damage 24-26 → 26-28 | Tier-6 line gets a flat buff. |
| Schism | Ferocious Ra'Shoth | Speed 5 → 6 | Tier-1 reaches the front a hex sooner. |
Two neutral-creature changes are worth knowing before your next map: Starchild now deals only 50% damage to adjacent targets with its basic attack, and Worldwatcher gained a passive that shields its stack from effects that instantly kill extra units on attack.

New Templates, Rotations & Timers
Four tournament-format templates joined the map generator: Jebus Tournament for Classic Mode (best-of-5 battles across week 1-2, always fought by your starting hero — a dead hero is an automatic loss), and Outcast Tournament (best-of-3), Mix, and Galaxy for Single Hero Mode. The competitive rotations changed with them:
- Classic Mode pool: Jebus Cross, Universe, Infinity, Last Fortress, Jebus Tournament, Arcade — Sand Clover and Arcade-era Harmony are out, and Jebus Cross plus Jebus Tournament are always in the selection.
- Single Hero pool: Helltide, Sprint, Exodus, Blitz, Outcast Tournament, Vendetta.
- Classic combat timers dropped from 120 to 90 seconds across leagues.
- Single Hero timers now scale by league — 80 seconds from Iron through Silver, down to 60 in Master — with a further 20-second cut on Outcast Tournament and Vendetta, offset by a +15-second daily bonus everywhere.
- Pick-and-ban order is now Player 1 ban, Player 2 ban, Player 1 pick, Player 2 pick, and side assignment is purely random instead of queue-time based.
Shorter timers reward pre-planned openings; the combat guide covers tactics-phase fundamentals that hold up under the 90-second clock.
What the July Updates Mean for the Meta
Winners
- Direct-damage mages — Sorcery doubled down twice: the skill buff and the specialist rescale.
- Grove — Hoplet and Phoenix buffs plus stronger laws pull the faction back from its post-launch slide.
- Dungeon — dragon damage jumped to 65-75 and the alt-attack direction bug that halved dragon damage is fixed.
- Necropolis quality of life — the raise preview tooltips and results-window recycling make the faction far easier to pilot.
Losers
- Base Summon Avatar spam — 3 guaranteed hits, lower damage, and a 5-round cooldown end the low-investment version.
- Necropolis tier-6 stacks — Dread Knight, Avatar of War, and Hollow Reaper all lost 20 HP.
- Schism Single Hero — Abyssal Communion caps at level 3/4/5 and summons fewer temporary creatures per level.
- Battle Magic sub-skill stacking — Authority sub-skills dropped from 20% to 15% scaling.
Expect the faction tier list to shift once ladder data settles; Grove and Dungeon are the factions most likely to climb, and the best builds page has Sorcery-flavored mage setups that benefit directly from Patch 12.
FAQ
What is the current version of Olden Era after Patch 12?
Version 0.80.34, live since July 10, 2026. It landed four days after Patch 11 (v0.80.31) and a same-day hotfix (v0.80.33). Patch 12 itself is a targeted follow-up: five crash, timer, and hotkey fixes, a Sorcery buff, an Arena draft correction, and template tuning on Sprint, Jebus Tournament, and Helltide.
Is the new Necromancy a buff or a nerf?
Both, depending on how you played it. Flexibility went up — you can raise any tier of undead even without that tier in your army — but the energy math tightened: raise costs are 4x higher per tier while energy pools only tripled (1,000/1,250/1,500 to 3,000/4,000/5,000). A full Expert pool now buys 2.5 tier-7 raises instead of 3, and 150 skeletons instead of 200. The Chronomancer elite class softens this by fully refilling your pool every day.
What happened to Summon Avatar in Patch 11?
The base summon was cut down hard: it now always falls after 3 hits regardless of skill level, deals 10-10 base damage, scales at 6/8/10 damage per Spell Power point instead of 12/12/12, and sits on a 5-round cooldown as a Tier-4 spell. In exchange, its sub-skills became real build paths — Avatar of Fury grants +40% damage, Avatar of Celerity grants +2 Speed and Initiative, and the new Summon Destruction sub-skill lets your whole army deal +50% damage to summoned creatures.
Is Sorcery worth taking after Patch 12?
Yes, for any hero planning to win through direct spell damage. The skill now grants +20/30/40% magic damage at Basic, Advanced, and Expert, and Sorcery specialists scale at 15% + 5% per 3 hero levels. A level-12 specialist now sits at +35% magic damage, up from +22% before the patch.
Which factions gained the most from the July 2026 updates?
Grove and Dungeon gained the most on paper. Grove received stat buffs across the Hoplet and Phoenix lines plus stronger laws after sliding down the meta, and Dungeon dragons jumped to 65-75 damage on the upgraded lines with the long-standing alt-attack damage bug fixed at the same time. Necropolis gained flexibility and growth but lost 20 HP on every tier-6 unit, and Schism's Single Hero Mode dominance was trimmed through the Abyssal Communion reductions.
