Alright Zar. Key points. 
1) there was only one attacking Karn. He had the staff. His name is varen. He also used the water magic. 
2) He and Karn are on Hemlock's head, unless they got knocked off, that part was up to Fox. 
3) the other one is haemos. He had a sword. 
4) Hemlock likely would have swatted Damian away if he got too close to haemos. 
5) Haemos is just a bit more protected. 
6) I don't mind you taking down Uriel(Flyer)  and Varen(Staff) as it would save Zero and Karn. 
7) But Haemos, I'm gonna need alive to make Hemlock go berserk. 

If you don't mind. We're gonna need to damage Hemlock and then my next post, maybe the post after will be a sort of farewell to the dragon. I feel the need to get rid of him. 
Do you have a dragon slaying blade? Or can we team attack with Zero and Damian.
