the way i beat lvl 15 is first do arrow wall and elemental arrows against the enemy's, then once u get 9999 mp then only use angels and draggys to destroy there castle then end will come and u should have the angles and draggys still there attacking him. mass send hobbits and angles and dragons when u can. the hobbits should slow him down. also shoot your arrows at him. remember to get turret and trap and the shield. if u have the shield then he only does 300 to your castle. took me 2 tries cause the first time i didnt use hobbits to slow him down
I think I've found a little glitch, I had a purple thing on me and when a bitter lunged at me instead of killing me he bumped me and the purple thing came off.
Not sure if it really works but has saved my butt sometimes so yeah. It could save your life too.(Still accepting tips and list of awards!)
