Frost dragon

Frost dragons lurk in the highest level Resource dungeon available, in the Asgarnian Ice Dungeon south of Asgarnia. The dungeon requires level 85 Dungeoneering to access, and inside are a total of 12 dragons to kill. Frost dragons attack with both melee and Magic (which appear to be water spells) as well as their dragonfire. Like all dragons, they are weak to stab attacks.

Killing frost dragons is highly profitable since their bones are currently worth each. Players may gain upwards of 0 per full inventory of bones, possibly more if using a Beast of Burden familiar.

Strategies
The most effective weapons to kill them with are the chaotic rapier, chaotic longsword, and the weaker brackish blade and korasi's sword, because of their high stab bonuses. The Zamorakian spear is also effective, yet dangerous unless super antifire potions or regular antifire potions are used along with Protect from Magic. It is worth noting that the dragonfire from frost dragons can be completely blocked by drinking an antifire potion and using Protect from Magic; an antidragon shield is not needed.

The fastest method of hunting them is to use armour with high melee defence bonuses with the Protect from Magic or Deflect Magic prayers activated. Suggested for this is Verac the Defiled's armour because of the hefty prayer and defence bonuses it offers. Wearing Karil's and activating Protect from Melee or Deflect Melee is not advised as their Magic attack is extremely accurate and easily hits through armour.

Another strategy is to use Ranged with proper dragonfire protection and Protect from Magic because no damage will be taken if the dragons are attacked from afar. Preference for Ranged armour is Void Knight ranged armour for its max hit increase or Armadyl for its stats.

Using Magic is not recommended as spells will splash very often.

Using a cannon is also highly recommended as it vastly speeds up kills. Despite the expenses incurred (Cannonballs), the total money made per unit time is much larger with a cannon than without one. For the same reason, constant use of Piety or Turmoil is advisable. As a secondary consideration, the faster the dragons are killed, the less time they have to inflict damage and deplete supplies (if applicable).

A decent way to bank Frost Dragon bones and replenish supplies is to use an Explorer's Ring 3 or an Explorer's Ring 4 to enable quick banking at Draynor Village, thus not having to pick up a cannon if you are using one. When returning to the dungeon, the cannon can be picked up and reassembled to prevent decay.

Players with access to Pack Yaks, Soul Split and Overloads can kill in excess of 150 frost dragons per hour, yielding an income of well over 2 million coins.

Some players choose to train at frost dragons because of the drops and the experience.
