Queen Black Dragon

All i need to do is show the Royal crossbow to the heat of the dragon, and i have it. All the guides i've looked up seem out dated. i only have 84 ranged, and my combat stats are pretty high. How should i go about killing her?

That explains all her attacks (all 8 of them) and everything else you can think of, Phases, setups & inventories etc.

 

Im very high melee, 99 str, and just below 99 all others, and cannot seem to beat her. I tried it with the best non degrading melee, and the best non degrading ranged setup. :/
