Skyshrine Infiltrator

The Skyshrine Infiltrator is one of the two Avatars you can control in Proving Grounds: The Underdepths.

The Skyshrine Infiltrator is a brigand, and seems to deal more damage (and thus grant a faster completion time) than the Guardian.

Combat Arts By Category
The Infiltrator begins play with three attacks (Thunderstruck, Poisoned Jolt, and Blunderbus) two temporary self buffs (Sly Retribution and Adrenaline Boost), and a self heal (Villainous Siphon).

Defeating the first boss, Veritor Buldama, awards your third temporary buff ability: Veritor's Deadly Round-up.

Defeating the second boss, Gikrakiis, grants the ability Shed Skin, a self cure.

Defeating the third boss, Aherin the Mighty, grants the ability Aherin's Mighty Slam, a strong attack.

Defeating Spikran Vergun grants you Strength of Skyshrine, a buff which boosts your abilities, and also allows you to cast while moving.

Defeating Kero'Var grants you Kick Up Dust, an Area-Of-Effect attack ability that also increases damage done to the target.

Finally, defeating the next-to-last boss grants you Grounded, a temporary buff that protects you from static storms, which is useful against the final boss.
