Frost dragon

The Frost dragon lurks 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.

Habitat
Frost Dragons are found in the Hidden Resource dungeon in the Asgarnian Ice Dungeon.

Strategies
The most effective weapon to kill them with is a Chaotic rapier or Chaotic longsword because of their high stab bonuses. The second most effective is 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 is a great way to fight as the prayers will not only nullify the damage from a dragon's magical attack, but will also reduce (not completely resist) the dragonbreath's damage. (Soul Split will NOT work here, you cannot sustain enough damage to keep yourself healed because you will be spending most of your time eating. That's how strong their magic attack is.)

Wearing Karil's and praying Protect from Melee or Deflect Melee is not advised as their magic attack is extremely accurate and easily hits through Karil's defense.

Another strategy is to use full ranged void while praying Protect from Magic or Deflect Magic as you will take no damage as long as you remain at a distance and have proper protection from dragonfire.

When using magic, fire spells are recommended due to of their natural weakness of fire.

Due to the fact that Frost dragons drop Frost dragon bones, killing them is very profitable since the bones are currently worth over 20K each, making over 400K per trip, and much more if using a beast of burden familiar.

The best way to kill them is to use full barrows armour with mage pray and to set up a cannon. The cannon can earn you up to 4,000,000 gp per hour, no lie.

Trivia

 * A glitch exists when one frost dragon initiates combat with one player. If another player attacks that dragon, it will continue to attack the first player and will not switch its attacks to the attacking player. The first player would not be able to attack another dragon until he or she retreated out of its range or the attacking player killed it. This glitch is even more invasive when cannons are used. This glitch has not been fixed yet.
