The game told me to attack 2 turtles so I figured I’ll ignore smaller ones since they keep spawning indefinitely and focus on the big ones. I spammed double attacks on the knight and all other allies attacked the turtle to remove its shields and then deal dmg - look how it’s done in expedition 33. I managed to kill one of them and got the second one to 50% before my team got wiped. One thing I don’t like is I never know if I fight with given amount of enemies or they will keep spawning.
