Overall
Severin is an Infection-stacking controller who converts marked enemies into weapons against themselves. His kit spreads Infection broadly with battlefield bursts and narrows it onto single targets through a roaming curse that punishes enemies for using active skills at all, feeding a growing stack count that his ultimate is built to cash in. Once enough Infection piles up, his ultimate seizes the most-marked enemy, turning them into a draining clone that fights on his side before reverting to a locked-down husk — or, against bosses, converting the same burst into scaling health loss instead. A successful lockdown elsewhere in his kit drains stolen energy into healing and permanently erodes enemy stats, while his signature item deepens the whole loop with bigger Infection payoffs, a higher stack cap, stat theft from any fallen hero, and a clone-based escape from death. His furniture speeds the setup, instantly maxing stacks on the first hit and letting him swallow summons outright without needing his ultimate at all.
Skills
Shifting Vessel
UltimateDeals AoE damage to all enemies, then possesses the most Infection-stacked enemy as a draining clone before reverting to a disabled husk; up to 4 clones can exist. Deals more damage per Infection stack, dispels buffs and grants invincibility on failed possession, and turns boss damage into scaling health loss.
Flowing Onslaught
ActiveTransforms into a flowing fluid that deals AoE damage across the battlefield, then reappears safely and applies an Infection stack to all damaged enemies, inflicting a lingering health drain. Also applies bonus stacks to the nearest enemy hero.
Core Injection
ActivePlants an Abyssal Core on the highest-attack enemy at battle start, then keeps shifting it to the least-stacked, lowest-health foe, applying Infection and AoE pulse damage each time. Marked enemies lose Haste and deal less damage while taking more Dragonspeak damage when using active skills; bosses take scaling health loss.
Noise Purge
ActiveLocks down the highest-attack enemy, disabling their skills and inflicting health loss while stacking Infection. A successful lockdown drains energy per Infection stack, healing Severin per point stolen, and permanently steals attack and defense from low-energy targets, up to two stacks; bosses take extra scaling health loss each use.
Signature Item
Origin Core
Adds Infection-scaled bonus damage to every hit, raises the Infection cap, lets Severin recycle fallen heroes' stats, and grants a near-death swap into a clone.
Furniture
Perfect Cohesion
The first Infection instantly maxes stacks, and possessing an enemy cleanses debuffs and grants Insight; infected summons can also be consumed without using his Ultimate.

Passive: Some of Severin's skills apply the undispellable "Infection" effect on enemy units, capped at 5 stacks. Active: Severin channels the Abyssal Current throughout his body, dealing Dragonspeak Damage equal to 800% of his Attack Rating to all enemies. He then possesses the enemy unit with the most Infection stacks (minimum 2 stacks), prioritizing the enemy hero with the lowest health percentage. Each time possession is triggered, only 1 unit will become possessed. If there are no suitable targets for possession, then instead, Dragonspeak Damage equal to 900% of Severin's Attack Rating will be dealt. The possessed enemy unit becomes a clone of Severin and is treated as an allied unit for 25s. Clones cannot receive healing but can use most of Severin's active skills (except his Ultimate), but cannot apply or receive Infection stacks. Clones inherit the possessed unit's Attack Rating, Defense Rating, and health, where the Attack and Defense Ratings will not exceed 450% of Severin's own stats. While possessed, clones lose health equal to 350% of Severin's Attack Rating per second, while Infection stacks and their effect of increasing the damage the unit takes remain active. Clones cannot be possessed. When the possession expires, the clone's remaining health is transferred to the possessed unit (leaving at least 1 health), but no higher than the health the unit had when first possessed. Additionally, Infection stacks are removed, and the unit will be unable to use active skills (except for normal attacks) for 9s. Up to 4 clones can be present on the battlefield at the same time.
Severin transforms into an Abyssal Fluid that flows across the battlefield, dealing Dragonspeak Damage equal to 350% of his Attack Rating to all enemy units. He then reappears in a safer location and applies a stack of Infection on all damaged enemy units, inflicting health loss equal to 250% of Severin's Attack Rating per second for 6s.
At the start of battle, Severin uses an Abyssal Core on the enemy hero with the highest initial Attack Rating, applying 1 stack of Infection. Each subsequent use of this skill transfers the Abyssal Core to the enemy hero with the fewest stacks of Infection while also applying 1 more stack on them. This effect prioritizes the enemy hero with the lowest health percentage. Whenever an Abyssal Core appears or transfers, it pulls nearby enemy units within a small range and deals Dragonspeak Damage equal to 300% of Severin's Attack Rating to them.
Severin moves near the enemy unit with the highest current Attack Rating and uses Abyssal Current to inflict health loss equal to 400% of his Attack Rating while preventing the target from using active skills (including normal attacks) for 9s.
Origin Core
Enhances: Law of EvolutionWhenever Severin deals damage, he deals extra Dragonspeak Damage equal to 350% of his Attack Rating for each stack of Infection the target has. If the target is a boss, he also inflicts health loss equal to 350% of his Attack Rating.
Whenever Severin deals damage, he deals extra Dragonspeak Damage equal to 450% of his Attack Rating for each stack of Infection the target has. If the target is a boss, he also inflicts health loss equal to 450% of his Attack Rating.
The Infection stack limit is increased to 6.
When any hero on the battlefield is killed, Severin recycles them, gaining 50% of their initial Attack Rating and Defense. The next time a hero is killed and recycled, if their initial Attack Rating or Defense is higher, the higher stat will be gained instead.
When Severin takes fatal damage, if any of his clones are on the battlefield, then he will transform into the clone with the highest current health and inherit its health value (capped at a max of Severin's initial health, and a minimum of 40% of Severin's initial health). The possessed enemy unit will recover its normal form. This effect can be triggered up to 3 times.
Enhances: Perfect Cohesion
The first time Severin applies Infection, the target will instantly reach the max number of Infection stacks. Each time Severin possesses an enemy unit, most of his attribute debuffs are dispelled and he gains 40 points of Insight for 10s. This effect does not stack.
If the enemy unit affected by Infection is a summon, then an extra 5 Infection stacks are applied, and once the max stacks are reached, Severin can possess the summon without using his Ultimate. When a summon is possessed, it is killed immediately. If the unit was summoned by a boss, then it will be killed immediately if its initial health is below 15% of the boss's max health. Otherwise, it will suffer health loss equal to 800% of Severin's Attack Rating.
Enemy heroes affected by an Abyssal Core lose 30 points of Haste each time they use an active skill other than a normal attack. This effect lasts 8s, and while active, the affected unit inflicts 75% less damage and health loss, while all Dragonspeak Damage they take is increased by 65%. This effect does not stack. If the target of Core Injection is a boss, then they suffer health loss equal to 200% of Severin's Attack Rating for each Infection stack they have.
If this skill successfully controls an enemy unit, then Severin will steal 150 Energy from the unit for each Infection stack it has. For every 50 Energy stolen, Severin recovers 7.5% of his max health. If the enemy unit has less than 70% Energy, then Severin will also permanently steal 35% of its initial Attack Rating and Defense (capped at a max of 350% of Severin's corresponding attribute, for up to 2 stacks). If the target is a boss, then every time this skill is used, the boss will suffer 30% more health loss for 9s for each Infection stack it has.
