The Mutations Update

Hi everyone!

This is the biggest content drop since launch. Two big systems, hundreds of new ways to break the game.

Patch is live now, and to celebrate - Codex Mortis is 20% OFF on Steam!

CODEX MORTIS

Before we dive in - here's short trailer showcasing the update:

Mutations are here!

We've spent the past few weeks rebuilding spells from the inside out. Mutations live on top of your existing skills and change how they work. New projectile patterns, new AoE shapes, new summon archetypes, new aura types. 249 in total, spread across 31 skills.

A taste of what's in:

Bone Spear:

• Bone Cone - five spears fanned in a 60° cone, instant

• Bone Carousel - eight spears in a 360° nova around you

• Boomerang Spear - every hit spawns a returning spear from the impact point

• Chain Bone - bounces between three enemies in range

Death Nova:

• Cemetery Cross - four-armed cross AoE instead of a circle

• Maelstrom - spawns a gravity well that drags enemies to the epicentre

• Funeral Tar - leaves a damaging slow patch on the ground

• Storm Nova - wide, low-damage shockwave

Skeleton Mage:

• Archmages - elite snipers (×4.2 damage, ×0.5 attack speed)

• Blood Slaves - triple the count, glass cannons, highest raw DPS

• Spell Crit - your summons start critting

Summon Rotbanner Herald:

• Frost Banner - heavy slow, 5 stacks

• Flame Banner - burn DoT

• Pulse Aura - discharges 5× damage every four seconds

Bat Swarm:

• Bombing Run - every fourth bat hit explodes

• Blood Explosion - bats explode on death

• Bat Vortex - bats orbit you instead of chasing

Gnashing Orbit:

• Jaw Carousel - quadruple the jaws, full 360° fan

• Heavy Chomp - slower, heavier, much bigger hit radius

• Six-Fanged Orbit - six jaws in a hex pattern

Animations Added

And it all moves. Every character and every enemy in CODEX MORTIS is fully animated - the necromancer's cast, the shamble of the restless dead, every summon and swarm that fills the screen. The chaos reads as cleanly as it plays.

Level-Up Rework - fewer cards, bigger picks

The level-up flow is rebuilt around Mutations. Three changes you'll feel immediately:

• 5 cards → 3 cards.

• Rarity now means breadth. Common upgrades 1 skill, Rare 2, Epic 3, Legendary 4, Mythic upgrades 5 skills at once - each rolling its own random stat. A Mythic card is five upgrades in one pick.

• Wider builds unlock higher rarities. If you're running 1–2 skills, the system won't roll you a Mythic - there's nothing to upgrade. The more skills in your loadout, the higher the ceiling. Theorycrafters who run full 8-skill rosters get the full range of rolls.

Base odds: 50% Common, 28% Rare, 14% Epic, 6% Legendary, 2% Mythic - but those are theoretical caps. Real chances scale with your build width.

Milestones (cards that grant Mutations) and new-skill unlocks still take priority over stat rolls. Nothing important gets buried under a random +damage.
