Hello, I tried Ms. Fizzle's Field Trip - Tier 5 and cannot figure out how to keep objective from failing. When the kids rearrange and are actually in the front line of the formation, the Alivebeard spawns and shoots projectile at kids, kiling them and failing the objective instantly. How can I prevent that?

Hi, thank you for response. I also tried putting Thalia with active Lightning Rod ability in the front column (front column formation was 2 kids + 1 slot for crusader) but the Alivebeard shot and killed one of the kids anyway - same result.. so not sure if one guaranteed crusader slot will help.. Alivebeard cannot be killed instantly, so he always shoots at least once.
