Operator overview: Corroserum

From Arknights Terra Wiki
Jump to navigation Jump to search

Corroserum is a 5★ Blast Caster who specializes in AoE and Debuff. As a Blast Caster, Corroserum has a linear range of four (five at Elite 1) tiles ahead and his attacks hit all enemies within the said range. While the unusual range makes him difficult to be utilized effectively in most operations and his DP cost of 33 (from Elite 1) being one of the highest of all Operators, Corroserum have high ATK at the expense of high attack interval, which means that his attack remains effective no matter how many tiles he hits.

Talent

Tactical Readjustment increases Corroserum's SP recovery rate which is disabled for 4 seconds when he attacks.

Skills

  1. Focus Overload buffs Corroserum's ATK while active but Stuns him for 10 seconds upon expiring.
    • Despite the drawback, Focus Overload surprisingly synergizes well with Tactical Readjustment as it would allow the skill to be charged much faster while Corroserum is stunned, since he does not attack.
  2. Conductive Corrosive Blast buffs Corroserum's ATK slightly less than Focus Overload and causes his attacks to Silence the targets for a short time while active, and can be manually deactivated at any point throughout its duration.
    • In a similar vein to Lappland with Spiritual Destruction, Conductive Corrosive Burst's Silence duration is longer than Corroserum's attack interval, thus allowing him to suppress the abilities of his enemies indefinitely so long as he keeps attacking them.

Operator Module

The BLA-X Module, Unerasable, increases the damage dealt by Corroserum against targets further away from him, up to 1.1×, in addition to increasing his maximum HP and ATK. Once upgraded, Tactical Readjustment's SP recovery buff is increased.

Base skills

Corroserum's base skills improve the efficiency of upgrade material processing while he is assigned to the Workshop.

  1. Corrosion Studies α increases the byproduct rate of upgrade material processing by 75% when he is assigned to a Workshop. At Elite 2, Corrosion Studies α becomes Corrosion Studies β with a higher byproduct boost of 80%.
  2. Corrosion Inhibition Tech guarantees that the byproduct will always be an Oriron Cluster.png Oriron Cluster when a T4 upgrade material is processed.
