easy but a long way to do it is morph back and forth dragonform / human. had like 16 critters when i finally got zagan. so i just morph back and forth when gotten him down. DONT FORGET TO USE DRAGON SHIELD pref max lvl. and just go in and out and 1 shot with fire spehere, and the repeat repeat repeat and lastly you will get all laid down.

just pray you where more lucky then me and have alot less then 16 critters. cause after every morph i was near death.

good luck.
