Frost dragon

'Frost dragon redirects here, if you meant the frost dragon from dungeoneering try: Frost dragon (daemonheim). 

The Frost Dragon lurks and derps in the highest level Resource Dungeon available to players (requiring level 85 in Dungeoneering to access. There are 12 dragons available to kill.

Frost Dragons attack with both melee and magic as well as their dragonfire, and they are weak to stab. The most effective weapon to kill them with would be to use a chaotic rapier, while the second most effective would be a Zamorakian spear (although if a Zamorakian spear is used, super antifires would have to be used). Wearing armour with high melee defence and praying Protect from Magic or Deflect Magic seems to work best to minimize the damage taken.
