The Magus Circle 1.1 Update: Keybindings, World Corruption and the Spellbook

What Changed in the 1.1 Update?

The first week of October brought the game’s first major version bump: the 1.1.0 update landed on October 7 alongside two rapid hotfixes (1.1.1 the same day, 1.1.2 on October 8). Together they are less a content drop than a replumbing of how the game feels — physics, input, and the systems you touch between runs.

The headline change of 1.1.0 is invisible when it works: the studio completely overhauled Unity’s physics system with their partners at Piktiv, changing how every spell and effect interacts with enemies. The patch notes themselves expect fallout — the announcement asks players to report unexpected behaviors in the Discord, because “a few interactions may have been missed.”

Keybindings and Settings Tabs (1.1.0)

The 1.1.0 update added new settings tabs for keybindings — movement, abilities, button press mode, and controllers. Before this patch, input was largely take-it-or-leave-it; now every core action can be remapped. The notes promise more settings tabs in future patches.

This matters most on Steam Deck and controller setups, where default keyboard-first bindings rarely fit. The Steam store page lists Windows, macOS and Linux with SteamOS support, and the controller tab is the first official acknowledgment that pad play needs its own tuning surface. For the full input picture — Button Press mode, drawing tablets and Deck play — see the controls and keybindings guide.

World Corruption Toggle (1.1.1)

The 1.1.1 hotfix added a feature with real replay value: after beating the game, you can toggle world corruption for all maps. Corruption variants were already in the game’s systems — the same day’s fixes call out a mismatch between Yomori and Corrupted Yomori boss ingredients — but the toggle makes them a deliberate post-game mode instead of something you stumble into.

The unlock condition is explicit: beat the game first. If the toggle is missing from your settings, that is why.

The Hub Spellbook Shows Every Upgrade (1.1.2)

The 1.1.2 hotfix (October 8) added the QoL feature collection-minded players wanted: the Spellbook in the Hub now lists every spell you have unlocked, along with all their upgrades. The same patch restored the missing text on tier 2 and tier 3 upgrades — the two fixes together make the spellbook the first place to check what a build path actually contains. For how spells fit into a run, see the spell list and the sigil drawing guide.

Planet Boss Fixes Across 1.1.1 and 1.1.2

The Yawm boss entries are notable: it is the first time the patch notes name a boss on Yawm directly, which is why the planets guide tracks Yawm as its own entry rather than a footnote to Elysia.

The 1.1.3 Hotfix (October 11)

The October 11 hotfix keeps polishing the 1.1 line: iFrames during revive (a death-protection window while getting back up), a new move for the First Leviathan, and — notable for mage watchers — the damage range of Chicha’s Reversed Aeon is now visible, her first mechanical appearance in the notes since her recipe line. Spell-side fixes cover Purification Beam, Disintegration Ray, Cross and Swift Gale amounts, and Lightning Blast initialization; planet bosses got a Yomori Leviathan fix (no more flying off screen) and a Yawm killbox teleport block. Performance got its own pass — Executioner Beam is capped to prevent crash-level lag spikes.

The 1.1.4 Hotfix (October 15)

Four days later the hotfix train kept rolling, and this one leads with the spell layer: the notes open with all spell synergies buffed, with Earthward Synergies getting its own fix further down the list. The run loop picked up real QoL: hints were added to the library, chests now despawn after 5 minutes — and when no upgrades are available, chests give mana and XP instead — Mana Burn now prevents mana regen (its values were also fixed), and Emergency Extract can be used before the boss, though no boss loot is included. The fix list covers the wrong DoTs applying, boss attacks continuing during pause, gestures sometimes not re-adding after a tutorial, and planet-side jank: the player offset after falling off platforms in Yomori is gone, alongside positioning fixes for Roaring Flames and Poppet Missile.

The 1.1.5 Update (October 19)

The newest patch leads with save safety: Steam Cloud saves are working — the notes say you should be able to load and use your save across any devices using Steam — with better backups for save files alongside. Anima rewards are now still given if your game crashes or you unexpectedly quit mid-run, achievements are tracked mid-run instead of at the end, and Puddle is acquirable in acts 2 and 3 (after beating the game) in case you missed him. The fix list touches builds directly: Chicha’s Overgrowth now spawns properly, the Exsanguinate + Ink interaction is fixed, Curse now receives damage buffs, Rebuke damage is fixed, and Prismatic orbs no longer fail to reach targets — plus Shifting Tide projectiles that stop on pause and a Wisp that is no longer FPS-dependent. What the Chicha lines mean for her kit is unpacked in the Chicha guide.

Balance Notes Worth Knowing

Two 1.1.1 balance lines change how existing builds play: Poppet now inflicts 2 random conditions by default (and “no more giant Poppets”), and Prismatic Gale now costs 1 mana for every 2 casts. If your build leaned on either, re-test it before trusting any pre-1.1 build notes — the meta data moved.
