Illuvium ILV $2.37 ▼ -17%’s Arena 1.18.13 patch raises Fire’s team-wide damage, strengthens Mud and buffs three Earth weapons that the studio said had fallen behind. The notes went up on the Illuvium Portal on Nov. 13, 2026.
“Fire and Earth are back in the conversation,” the official @illuviumio account said in a post on X announcing the update. “There’s a lot moving in this one.”

There’s a lot moving in this one.
Full breakdown ↓
The patch notes open with the studio’s stated aim: “This patch gives Fire and Earth a reason to come back. Fire’s team-wide damage goes up, Mud hits harder, and the Earth weapons that fell behind get some help.”
Fire gets a bigger mid-tier jump
Fire’s Team Attack Damage moves from 5% / 15% / 20% to 5% / 20% / 25%. Fire units still receive double, so their bonus goes from 10% / 30% / 40% to 10% / 40% / 50%. The (6) bonus of Pure Damage equal to 1.5% of the target’s Max Health is unchanged.
“Fire hasn’t had a real place in the meta, and that left the board without a natural counter to some of the stronger Water and Nature builds,” the patch notes said. “Fire teams now hit noticeably harder from (3) onward.”
Mud’s stolen Attack Damage and Omega Power rises from 25% / 35% to 30% / 40%. Its (3) effect, which grants Attack Damage and Omega Power to the three closest allies when a Mud unit is vanquished, goes from 20% to 25%.
Ophisto slowed down
Ophisto (Squid, Stage 3) now starts fights with 10 Energy, down from 30.
“Ophisto’s lightning often fired before the fight had properly started, and an early kill let it chain into extra casts,” the notes said. “Its first cast now comes a little later.”
Earth weapons and amplifiers
Earthgrasp Sceptre’s Energy Cost falls from 200 to 180. “Our last Energy Cost increase overshot. We’re walking part of it back,” the notes said.
Quake Maulers’ Attack Damage goes from 125 to 140. While shielded, its attacks now reduce Physical Resist by 12, up from 10.
Vinebound Cleaver’s Omega Attack Speed rises from 25% to 30% and its Omega Physical Attack Damage from 80 to 100. “The Cleaver itself was underpowered, so we’re buffing the weapon rather than its amplifiers,” the studio wrote.
Seven amplifiers went up. Reinforced Rampart on Quake Maulers now adds a 500 Shield on Omega instead of 350. Searing Echo on Flamewarden Staff deals Omega Energy Damage of 20% of Max Health over four seconds, up from 12%. Aftershock on Ember Buckler goes from 10% to 15% of Max Health within 20 hexes.
On Shadow Maul, Shadow Acceleration’s 80% Attack Speed buff now lasts six seconds instead of four. Enhanced Tremor’s Omega damage moves from 800 to 1,000. Petal Detonation on Sprout Guard rises from 850 to 1,000 Energy Damage on Shield expiry.
Reflective Barrier, also on Sprout Guard, was cut hard. Its Reflected Pure Damage per Shield hit drops from 25 to five.
The studio said the amplifier “was reflecting damage onto more enemies than intended, which turned a frontline Sprout Guard into a damage source for the whole board.” It called the change “a temporary reduction while we work on a proper fix, and we’ll revisit it once that’s in.”
Void Reactors trimmed
The notes said augments “that were taking over lobbies come down a notch, and a few that were sitting unused get buffs.”
In the Forge tier, Immunis Void Reactor’s Immunity and Omega Power window shrinks from the first 15 seconds to the first 12. Conduction Void Reactor now gives the three closest allies 20 Energy on start instead of 30, and its starting Shield falls from 5% to 2% of Max Health. Inversion Void Reactor drains seven Energy on Omega, down from eight.
Synchronizing Pulse Reactor converts 25% of Attack Physical Damage into Energy Damage, up from 15%. Converging Impact Reactor’s Physical Attack Damage gain goes from 1% to 1.5% of Max Health.
Primal Omega Reactor now grants three Energy Regen for 10 seconds on start, then 10 Omega Power. The studio also fixed its tooltip. The old one listed five Energy Regen for four seconds, while the actual effect was four Energy Regen for five seconds.
Legendary changes
Limitless Surge “front-loads more of its power, but ramps more slowly,” according to the notes. Initial Omega Power doubles from 10 to 20. Its gain every five seconds falls from +10 to +5 Omega Power and from +10% to +5% Energy Resist Piercing.
Hyper Striker Protocol’s Piercing rises from 20% to 30% and its Attack Speed from 25% to 35%. Nova Heart’s Thorns go from 30 to 50, with its 30% Max Health component unchanged.
Temporal Guard’s On Omega Shield and Heal climbs from 250% to 350% of Energy Cost.
The update comes about two and a half weeks after 1.18.11, which the portal dated Oct. 27. Earlier, in 1.18.3, @illuviumio said Earth’s Hyper bonus had moved to Physical Resist and composites were capped at three.
