All,
Sounds like I was doing it the really hard, float-like-a-butterfly way.
The first time I tried to do it y'alls way that dinklestein would consistently fly out of range (because what does a fire howitzer dragon care about range?)
I'll have to try it the "split method" way of killing the dragon in midair. It was just pissing me off so much as I actually chased his purple butt around the entire platform, waiting for him to get in range.
I never tried it again that way, instead insisting on killing the rider first while grounding totems kept me safe from the dragon above. The HARD way!
I'm proud of my guys anyway.
