Apex Contagion is the name of Caustic Prestige Skin that becomes a Mythic appearance for this legend. It is available for purchasing as a Tier 1 in the Apex Legends in-game store at the price of 150 Heirloom Shards.

Apex Contagion skin has 3 Tier levels that upgrade equipment with new visual features. For example, Tier 2 enhances weapons and green color armor. But the main difference of T2 from Tier 1 is the skull-shaped mask displayed on the plate helmet.
Caustic Prestige Skin has one of the coolest finishers in the entire Apex Legends game. Just for this one feature alone, players should collect this equipment. It’s important to note that this finisher is available to gamers only after reaching Tier 3 rank.
Equipping this appearance, the legend lunges at the opponent, knocking him to the ground. Immediately after this, Caustic uses his main weapon – the acid mask. The hero removes his helmet to use the Toxic Scream ability and dissolves the enemy’s body in acid. An additional “wow-effect” is provided by the hero’s transformed face, which significantly differs from the familiar plague doctor look.
