A big Auto Chess update: the legendary Demon Warlock Zelatun joins the roster, the Myriad Arms Ring relic is added, Demon Power is heavily reworked, mana regeneration rules are unified, and the Drodo Fusion event begins. The patch number and date are not stated in the source material.

New Hero

• Zelatun, Lord of the Abyss — Legendary, Demon race, Warlock class; he does not receive the Warlock class trait effect. Health 1250 / 2500 / 5000, attack 100–160 / 200–320 / 400–640, armor 10, magic resistance 20%, attack interval 1.5, attack range 160.
• Zelatun — Demon Gate (active skill / Battle Cry): he opens the Demon Gate, which continuously summons random Demons at a star level equal to the skill level. Summoning continues until the gate runs out of energy or the gate is destroyed. Max summon duration 12 sec, min 8 sec, summon interval 4 sec.

New Relic

• Myriad Arms Ring — grants 20 Spiral Forgers. You can spend them to replace an item with a random item of the same rarity: Common — 1, Uncommon — 2, Rare — 3, Epic — 4, Legendary — 5. Spiral Forgers last only 10 rounds; when they expire, the remaining amount affects the chance to get 0–2 Dormant Crystals.

Hero Changes

• Nightmare — Orb of Devastation no longer disappears on hit: it keeps searching for new targets until the skill ends, then returns to the caster and restores health to them.
• Hawk — allied Hawks no longer trigger each other's Eagle Eye when using active skills; with several Hawks on the board they can no longer launch each other's ability.
• Helicopter — the extra normal attacks from Bullet Hail no longer trigger on-hit effects (for example, they cannot trigger the armor reduction from the Erosion Blade normal attack).
• Exile — Split: illusions now inherit the original's current health percentage but deal only 50% damage (for example, Mjollnir on an illusion deals only 100 magic damage). Max number of illusions 3 / 5 / 7 → 5 / 7 / 9, damage taken by secondary illusions 200% → 400%. Clones can no longer be revived by Cave Nugget.
• Fox Swordsman — Foxriken now always hits the target, fully ignoring evasion.

Item Changes

• Magic Mirror — the mirror figures from Inner Demon now inherit the original's current health percentage.
• Eye of Azes — the Ice Curse effect where the owner's damage reduced the target's attack by 50% has been removed.
• Hat of Clarity — rarity changed from Uncommon to Common.
• Herald's Crystal — no longer triggers the Shaman synergy transformation.
• Purifying Blade — also no longer triggers the Shaman synergy transformation.

Synergy Changes

• Demons — Demon Power has been heavily reworked. Stacks are now calculated dynamically in real time and update whenever Demons die, are summoned, are revived, transform, or fall under enemy control. Identical Demons now also grant stacks, up to a maximum of 7. For example, if two Hell Knights activate the Demon synergy at the start of a battle, each gets 2 stacks, and after one dies 1 stack remains. Zelatun's summons are counted separately by the name of the summoned Demon: two Zelatuns = 2 stacks, a third Zelatun makes it 3, and a summoned Fallen Witcher is counted separately for 1 stack. If Demons and Witchers are active at the same time, Demon Power counts all allied Demons and all enemy Witchers, using the total count rather than the number of distinct Demon types (maximum 7 stacks). The current stack count is now shown directly on the synergy icon.
• Witchers — Witchers now interfere with the enemy's Demon synergy count. If the opponent did not use a Demon mage to activate Mages [4], a Witcher can additionally activate Demons for them and thereby break Mages [4]. If the opponent uses one Demon mage but cannot activate Mages [4] because of Demons, a Witcher can disable their Demon synergy and instead help them activate Mages [4].
