Krogan Shaman Adept

Krogan are large bipeds native to the planet Tuchanka, a world known for its harsh environment, scarce resources, and vicious predators. Until the invention of gunpowder, the leading cause of krogan fatalities was "eaten by predators." Though slow, krogan can take tremendous damage in combat, allowing them to inflict grievous harm with impunity.

Armored like a tank--and as slow as one--an angry krogan has more going for it than the species' infamous belligerence. It should come as no surprise that a krogan dishes out as much punishment as they're able to take on the battlefield.

General Notes

 * The Krogan Shaman has access to Shockwave and Warp, making him the only krogan truly able to take down enemies without firing a shot. This alone makes the Krogan Shaman a great class, but his ability to carry heavier weapons and endure more damage than any other race makes said class very well rounded.

Cerberus

 * Shockwave is useful for exposing Guardians or dealing heavy damage around chokepoints or large squads of enemies.
 * Warp serves as your anti-armor/barrier power and can be detonated with Shockwave to devastating effect.
 * Be wary of Phantoms: as with all characters that cannot dodge, Krogan Shaman are more prone to being impaled.

Collectors

 * This is where you will shine. Since all enemies have barriers and/or armour or health, every single enemy is vulnerable to your biotics in some form or another.
 * Shockwave will suppress the weaker enemies such as the Collector Troopers, and Abominations, while Warp will weaken armor and set up Biotic Explosions.
 * Combine the Shaman's powers with an Acolyte, or other anti-shield/barrier weapon, and you can easily send the Collectors packing.

Geth

 * Barrier is useful to help combat the geth's many staggering attacks.
 * The force effects of Shockwave only affect Rocket Troopers, Hunters and standard troopers.
 * To fight armored geth enemies or clustered groups, it is best to combine Warp and Shockwave for the most powerful Biotic Explosions possible.
 * Geth Bombers can bomb you into submission very quickly as Krogan aren't exactly nimble nor small: be wary.

Reapers

 * Your powers will do serious damage against this faction. Shockwave will suppress the Husks, Swarmers, Cannibals, and unshielded Marauders, while Warp will adequately deal with every other foe. With a good weapon combo you should have no trouble dealing with the Reapers, no matter what they throw at you.
