In the game, when ever one of your party members manages to land a critical hit or hit an enemy with
a skill that has an element the enemy is weak to, they gain the smirk status effect.
It basically increases the effect of buffs and it also heals all allies if they have smirk status.
So I was at the grocery store trying to reach for some small garbage bags on the top shelf way in the back. Instead of going all the way downstairs to find someone to help me I grabbed a broom and pulled it down. Putting the broom back I said, "Thank you for your service".
