Ice strykewyrm

Ice strykewyrms are slayer monsters that require a Slayer level of 93 to kill. They are located near the Muspah cave. They have the unique drop of a Staff of light.

These are an assignment from the slayer masters Duradel/Lapalok and Kuradal and primarily to those who own a Fire Cape. If a player does not have a fire cape then they're able to unlock the task for 2,000 slayer points. Kuradal's chance of assigning Ice Strykewyrms is higher than Duradel/Lapalok.

Like other Strykewyrms, Ice Strykewyrms can only be killed when they are assigned as your current slayer task. Unlocking the ability from Kuradal does not allow players to kill Ice Strykewyrms off-task, it merely allows for them to be assigned as a task without the player owning a Fire Cape.

Getting there
The strykewyrms are located in the cave of the quest The Tale of the Muspah, and you must also complete the quest in order to fight these creatures.

The quickest way to gain access to the cave of the Ice strykewyrm is the fairy ring code DKS, which sends you right beside the cave. Go into the cave on top of the hill. Go as far right as you can immediately upon entering the cave. If there is water coming out blocking your way you need to go back and enter the room just northwest of the cave entrance. Go right and jump over the first stream. Keep going and block the second stream using a SPADE on the mound next to it. Now go back and the cave will be free to enter.

Attack styles
Ice strykewyms are not that powerfull they wont hit on you much so u dont have to take to good defence stuff

Strategies
Despite requiring level 93 slayer, these creatures have remarkably low defence, and may therefore be killed effectively by many different methods, other than the fire weakness. Using an abyssal whip seems to be more effective than using a godsword, as high hits are very frequent. Proselyte gear and prayer is also an effective alternative.

Ice strykewyrms are weak to fire-based magic; using Fire surge can allow you to hit extreme damages of over 1100 (while wearing a Fire cape, Hexcrest, Staff of light, Arcane stream necklace and drinking an Extreme magic potion/using the Wolpertinger's Magic Focus scroll) and is apparently the most effective way to kill these creatures. If you don't have the required magic level,an alternative is using Fire Blast or Fire Wave; these will also deal a fair amount of damage. Conversely, casting ice spells from the Ancient Magicks spellbook will heal the Ice strykewyrms. .

Using Magic or Ranged is safer than using Melee. If Protect from Magic or Deflect Magic is used and the player is standing at least one square away from the wrym beside a wall or stalactite, no damage will be taken (when standing beside an obstacle the wyrm cannot use its burrow attack).

Trivia

 * Ice strykewyrms, along with the other strykewyrms, are the first monsters to incorporate particle effects.
 * Jagex has proposed that players who are unable to get the Fire cape are given the option to purchase the ability to kill Ice strykewyrms from a Slayer master with their Slayer points, while the Fire cape makes players more effective at fighting Ice strykewyrms. This has been put into effect along with the Shattered Heart update in 3 March 2010.
 * As of 3 March 2010, players wearing a Fire cape while fighting ice strykewyrms deal 2.0x damage with fire-based spells. Additionally, players wearing a Fire cape deal 40 extra damage with any combat style.
 * Players who are not wearing a firecape deal 1.5x damage with fire-based spells.
 * Strangely enough, the strykewyrms seem to look like the 'Bogimoray', a boss from the Lost Odyssey game.
