Theorem Contagion is an Arcane Enhancement for Warframes that grants them the ability to spawn orbiting globes upon contact with the area of effect caused by 
Residual Boils, 
Residual Malodor, 
Residual Shock, or 
Residual Viremia. These globes will target the closest enemy within 15 meters, dealing damage and increasing their vulnerability to the globe's damage type.
Can be sold for 
1,000.

Notes[]
- Activates using Residual Arcanes.
- Stacks are gained on time with the area's damage ticks, and multiple areas increase the rate of stacking.
- Different elemental Residual areas will result in separate stacks.
- Orbiting globes resemble
Nova's Null Star particles with trail colors matching the Residual's element. - Directly affects damage type modifiers of the enemy's health, shield, and armor class.
- For example, an enemy with Infested Flesh has a -50% Cold damage modifier which means that incoming Cold damage will be halved. Equipping a max rank Theorem Contagion with Residual Malodor will make it so that the enemy will have a 50% × (100% + 200%) = 1.5x Cold damage modifier
- For example, an enemy with Infested Flesh has a -50%
Patch History[]
Update 31.6 (2022-06-09)
- ARCANE STAT CHANGES PER RANK
We’ve adjusted the values of older Arcanes with the goal of making lower rank Arcanes more viable, and more desirable while collecting as a result. In short, there are three stats that each Arcane tends to have (speaking generally) -- for example, a percentage chance, a stat buff, and the duration of the buff.
Certain Arcanes increase all of these stats per rank (making them scale exponentially), but we are changing it so that only one stat is affected by rank (making it scale linearly). The other stats will now be at the max-rank value regardless of the Arcane Rank, thereby buffing lower-rank Arcanes as a result.
- Theorem Contagion
Standing in a zone created by a Residual Arcane creates a globe that orbits the player every 2s. The globe will strike the nearest enemy within 15m dealing 150 (was 25) damage increasing their vulnerability to the globe’s damage type by 25%/200% for 6s (was 1s). Globes will persist for 30s (was 5s) upon leaving the zone.
Update 30.8 (2021-10-04)
- Fixed incorrect duration/debuff percent values being used for Theorem Contagion.
Update 29.5 (2020-11-19)
- Introduced.
