Frost dragon

Frost dragons make lair in the Asgarnian Ice Dungeon resource dungeon. The dungeon requires level 85 Dungeoneering to access, and inside are a total of 12 dragons to kill. Frost dragons attack with all three combat styles, as well as with dragonfire. Like all dragons, they are weak to stab attacks.

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

On 17 October 2011 the mechanics of Frost Dragons received an update. They were given a ranged attack, similar to Mithril Dragons, as well as a new rebounding effect. Each Frost dragon will attack with EITHER their ranged or magic attack for the entire fight; which style it will use depends on whichever attack is randomly used FIRST - so keep an eye on the first attack, and pray accordingly for that kill. When fighting Frost Dragons, a small blue orb will appear and start circling the dragon. It is important that you do NOT attack while the orb is out, as it will rebound any damage you would've dealt 100%. Therefore, it is important that you have your auto-retaliate switched OFF when fighting these dragons; when the orb appears, click away from the dragon to stop attacking and wait. The orb will circle 3 times before it disappears, after which you can resume killing your dragon. Cannons will not deal damage to the dragon while the orb is active, and the player will not receive any damage from fired cannonballs. This makes frost dragons a slightly tougher monster to fight, but should not heavily hinder any legitimate player trying to kill them. Jagex also created randomly appearing frost bone spawns. These spawns are unobtainable, even by Telegrab --this will cause bots to 'try' to pick up the bones, effectively incapacitating them.

Strategies
The most effective weapons to kill them with are the chaotic rapier, chaotic crossbow, chaotic longsword, as well as the lower powered brackish blade and Korasi's Sword, because of their high stab or range bonuses. The Zamorakian spear is also effective. Drinking an antifire potion and using Protect from Magic will completely negate the damage of a frost dragon's dragonfire, therefore, an anti-dragon shield is not needed. Their magic attack is very accurate, making it incredibly dangerous for players not using Protect from Magic. Regardless of how you will kill the dragon, ALWAYS use Protect from Magic; a good ranged or melee setup would block off most of the ranged attacks.

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. Soul Wars cape or Fire cape are both excellent capes to choose, due to the def/prayer and def/str bonuses, respectively. Trying to tank their magic attacks and pray against melee is NOT advised as their magic attack is very heavy hitting and highly accurate. Even with incredibly high magic defence stats, players will take heavy damage. Players with lower than 80 defence should NOT use melee as it wastes a lot of food, and the dragon can hit up to 220 with melee. Also, players with a large amount of lagg should NOT kill them, because depending on your max hit and attack level, you can end up getting killed without you even knowing it.

After the October 17 2011 update, it is now advised not to use range. This is because ranged armour has an extremely low ranged defence and as of October 17 2011, Frost Dragons now use a ranged attack which hits upwards of 220 lifepoints. Players can also try strong ranged defensive armor, such as Karil's or Armadyl sets if they want to. A good defensive setup however, finds that using Initate armor has LESS ranged defence then Black d'hide, so use ranged at your own risk. It still has a nice ranged and magic defense though.

Using Magic is not recommended as spells will splash very often, except Storm of Armadyl coupled with an Armadyl Battlestaff. However, don't expect to come anywhere close to profiting due to the approximate 2,700 coins/cast you'll be using. Also, the heavy ranged damage usually causes problems due to the fact that Magic armor has even less ranged defense then ranged armor.

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). After the 17/10 update, cannons will instantly decay upon leaving the caverns. Also note, when the Frost Dragon uses its recoil attack, no cannon damage will be reflected back to you. Also, the cannon is recommended because other players will set cannons up, and those cannons can potentially steal your dragon, so using a cannon makes it show who is attacking it.

A decent way to bank Frost Dragon bones and replenish supplies is to use an Explorer's Ring 3 or 4 to enable quick banking at Draynor Village. Along with that, players coming from the north can use the small church nearby to recover any prayer points if needed. An even better way is to use a Ring of Duelling paired with a Ring of slaying to give almost instant access to a bank and fairy ring. Since Mudskipper Point is the first on the fairy ring travel log, you can travel there very quickly. They can also use the Teleport to House tab if their PoH is in Rimmington. This is effective, but players will need to stock on Teleport to House tabs.

Players with access to Pack Yaks, Soul Split and Overloads could kill in excess of 200 frost dragons per hour, yielding an income of well over 2 million coins. Due to the recent updates the crowding issue should mostly be resolved.

After the 17/10 update with the new ranged attack, the Frost Dragon will only use either its' ranged or magic attack for the entire fight. The chance is random, so it is advised to change to the corresponding prayer depending on the FIRST regular attack, whether it is a ranged attack (thin blue projectile) or a magic attack (Water spell), and you will not receive any damage from the regular attacks.

NOTE: Logging out in the Frost Dragon lair will make you end up outside the resource dungeon entrance.If you die in the Frost Dragon lair your gravestone will spawn outside the resource dungeon entrance. Your cannon will stay inside the lair, it will not be activated until the player returns and fires it.

High population
After release of the Dungeoneering skill, players noticed that Frost Dragons were an efficient way of making money. Soon players flocked to the resource dungeon, making killing difficult. The lair was then known for its obscenely high quantity of bots and cannons. These two factors have, over time, greatly reduced the amount of money made per hour.

Frost Dragons were updated on October 17, 2011 in an effort to combat the high amount of bots.

Trivia

 * Frost dragons were the only monster in RuneScape that lived exclusively in a Resource dungeon. (Apart from Dungeoneering floors). This has now changed due to the release of A Clockwork Syringe.
 * Despite being a dragon covered in frost and ice and using water spells, they still breathe the traditional dragonfire.
 * The dragons have a chance of dropping 1337 coins, which is "leet"-speak for "leet" or "elite".
 * Although Frost dragons are dragons, they cannot be assigned as a slayer task by any slayer master.
 * Frost dragons are the only dragons that do not have a second drop; chromatic dragons drop dragonhide and metal dragons drop metal bars.
 * In the October 17, 2011 update, Frost Dragons were changed significantly; Jagex developers hoped this would combat the heavy botting.
 * Along with their update to their mechanics to combat bots, Jagex also created randomly appearing frost bone spawns. These spawns are unobtainable, even by telegrab. This is another thing made to stop bots, the way they are programmed make then pick up the bones by variables, the bones dropped by the dragons have the same code as the bones that can't be picked, so the bot will be stuck if it try to pick those bones.
 * Due to the addition of attempts to stop the bots, the Frost dragon spawns have not been moved. One spawn on one side has a dragon stuck in water, and another (because of the extra rocks to block the bots from telegrabbing/getting the bones) will be stuck there. They can still move out, and their drop is still accessible.
