i posted this in the other topic about end game dragon flight did you save your dragon armour that you picked up along the way you should replace what they give you with it makes it alot easier when it gives you + stats i think my dragon had 1200 hp and like 600 or 800 mana when i completed it fireball was pretty much maxed i could use firebreath all i wanted just needed to hold a sec to get enough mana up to do either the fireball or alittle longer for the big bomb eye of the patriach?. dragon armour doesnt take up back pack space so hold onto it also you cant stay still keep on the move use ur shield you flying wyvern is very nice to have up at all times and remember you can use both the healing spell and potions for your dragon (healing wise dont know if armour /dext / etc work)
