Ice strykewyrm

Ice strykewyrms are slayer monsters that require a Slayer level of 93 to kill them. 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 and Kuradal and only to those who own a Fire cape. Kuradal's chance of assigning Ice Strykewyrms is higher than Duradel's.

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 strykewyrms have 4 types of attack: Melee, magic, freezing spell and burrow. If the player is within one square of the wyrm, it will use all 4 attack types, but from a distance it will not melee. The wyrm uses the freezing spell occasionally (which looks like an ice barrage), making the player unable to move for around 3 seconds and cancels the player's next attack. Simply clicking the wyrm will resume attacking immediately.

The Ice strykewyrm's strongest attack is when it burrows underground during battle and then pops back up, dealing 30 damage to anyone around it. The Ice strykewyrm becomes invulnerable during this time, so attempting to attack it while it is burrowed is futile. This attack can be easily avoided by quickly moving two steps away in any direction. The further away the player is from the wyrm when it burrows (such as when maging from a distance) the easier it is to avoid this attack. Standing beside or close to a stalagmite can actually negate the burrow attack from being used on you, although moving away from the burrow is easier. It can also use the burrow attack if you walk on it and stay there for a couple of seconds so it is recommended not to do so.

Strategies
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, and using Fire surge can allow you to hit extreme damages of up to 1800 (while wearing a lava cape, unconfirmed), and is apparently the most effective way to kill these creatures. If you don't have the required mage 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 .

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.
