#1500 renown in the crucible
Renown is earned by making kills and earning medals with any weapon or ability while The Last Word is equipped, but lost by dying. Streaks and multikills are worth a large amount of renown. Renown earnings are 1% for non-headshot kills, 2% for headshot kills, 5% for kill streaks, 1% for assists, and 3% for winning.
This step is easily done in SRL as every race completed counts as a "win" regardless of placement, although progress is still lost for dying. Completing 34 SRL races is enough to complete this step.
#1 Valus Mau'ual
#1 Valus Tlu'urn
A variant of Shield Brothers at light level 290 with the Epic modifier must be completed. A shotgun must be used to deal the killing blow to both the Shield Brothers for it to count as a kill.
#Wait for Tex Mechanica's committee to complete its selection process .
#500 renown with shotguns
Unlike the first step, renown is no longer lost upon death. Crucible kills yield significantly more renown than majors or ultras.
