So I was doing the daily with the Crimson Lasher today, and trapped one of the scorpions because my pet was about to die, and while trapped he kept casting the lava pool spell your lasher needs every 5-15 seconds. I doubt this is intended, as he was casting it while completely frozen. I can only confirm for freezing trap right now, but it's definitely easier than going around and killing many different ones and letting them kill your pet or you. Hope it helps!
Edit/update: I discovered that this only works in a very special way. They have to cast one of the pools BEFORE you CC them, and it also works with Wyvern Sting. I cast Wyvern Sting right as I engaged him and nothing happened, he just stayed CC'd, but when I let him cast a pool first, he continued to cast pools. I believe this works the same way with freezing trap. Screenshots soon.![]()
