Level 200, +2e, Team Triage Tank 9 lucky skill. Not terrible as long as you don’t get nat crit too many times and the gauge refreshes cooperate (especially on bar 3). Get a flinch or two on bar 3 and you’re set. Apparently Endurance wasn’t needed so this can be done without an overcap but I wouldn’t risk it personally. You could also instead grid Aggravation to make the bar 3 flinches more consistent.
