Now you have "Guard debuffs", whatever that is. Just thinking of the logic behind the term makes my hate of the game reach dangerous thresholds.
Probably, Guard debuf it means barriers and def buff (like Dana) or reflect (like Athena and Hades).
Making it -- like "Crisis measures" and "Anti-crisis measures" -- have the interchangeability with "Guard buffs" the five-star Tiamat hates?
I'm guessing guard debuffs are stuff like Bathory's dancing blade effect which lowers the defense? This is actually good since Charlotte won't have to rely on their shield to be up. I found that she could already 1 shot super tanky shielded Dana's when they are the last unit hanging before the ignition update. This will prove interesting.
