Maybe add a diagram of teams into the corners. Representing all 5 characters of either team. Nothing fancy, just some dots would do. These dots would change color whenever they are attacked by something (ex. Andrea leader gets stunned so middle dot turns from white to yellow) .
White: normal (no buffs or debuffs)
Blue: bonus hp
Red aura: bleed
Orange aura: burn
Green aura: hp regain (heal over time)
Yellow aura: confused
Blue aura: focus
Decapitated: blacked out
Any other statuses I forgot I apologize.
Reason for idea: I just can’t ever see the decapitate icon because it’s hidden behind my characters.
