R5-D4 Character Quest - Deflective Ward not counting

Here's how I was able to do it with the New Cassian team (Need Vel and Cassian and Kleya) without Jocasta or SM-33 - Had to do it in Conquest as well with the F-34T Training Droid data disk farm out 5 times.

How to Undermine the Enemy (Step-by-Step)

1. Utilize Kleya: Use Kleya’s special abilities to apply Undermine early to key targets for 1-2 turns.
2. Trigger with Cassian (Under Cover): Use Cassian's basic attack ("Clem") on a target that already has Undermine to apply Undermine to another target.
3. Spread the Effect: Continue using basic attacks with Cassian on already Undermined targets to spread the effect to the entire enemy team.
4. Vel Basic Level 7: On her turn, if all enemies are Undermined, Rebel fighters gain Protection Up(50%) for 1 turn and Vel gains Deflective Ward for 1 turn or until she receives damage.

Hope this helps
