Grunt: Rite of Passage

Grunt travels to Tuchanka to undergo the Krogan rite of passage.

Walkthrough
Commander Shepard and Grunt travel along a highway to the keystone, where the rite takes place. The first several waves are comprised of several animals that utilize melee attacks. It is best to stay out in the open during this portion of the mission.

Eventually, a Thresher Maw will appear. Shepard and Grunt kill the Maw and are ambushed by members of Clan Weyrloc. Shepard may pick up the combustion manifold for Tuchanka: Combustion Manifold at this time. Upon his return to Tuchanka, Grunt becomes a full-fledged member of Clan Urdnot.

Rewards
Grunt's loyalty is earned and his Fortification power is unlocked.

Trivia
After this mission, several krogan will comment on the thresher maw Shepard killed, stating that it has not been done since Urdnot Wrex underwent the trial himself.
