Cheat sheets that run it
Tips that save runs
- Continuity and Primed Continuity: both add Ability Duration, so the bonuses stack for longer buffs and crowd control.
- Buff and crowd control frames that want more uptime and hate being stuck on the floor.
- Frames that get knocked down a lot in high level content.
- Constitution has max rank 3 and can be traded.
- The drop is on the Nightmare Mode reward table, Rotation C.
Mistakes that waste runs
- Looking for it in normal missions. It is a Nightmare Mode reward.
- Running it for the knockdown recovery alone and ignoring the duration bonus.
