A bit of a turn-off I know. When I saw that red Dragon first time, I was reluctant to approach at all.

After mastering the arts of preperation & barrelmancy, also having my beholder-bottle at the ready - I was eager to fight him.
But he phased out anyways. A bit of a disappointment.
Was looking forward to at least one encounter that would walk all over me.
And to find not a single way how to beat it - since it was not intended for us to prevail here.
But our disrespectful attack towards a gigantic being that should trample us down to seize, had disappointingly less consequences. :|
