Ice strykewyrm

Ice strykewyrms have the second highest slayer requirement of slayer monsters outside of Daemonheim (after Ganodermic beasts and Legiones), requiring a Slayer level of 93 to kill. They were introduced into the game along with jungle and desert strykewyrms, and they are the only monster that drops the staff of light.

They can only be killed when assigned on a slayer task, with the exception of one kill needed to complete a Fremennik Elite Task. Players must complete The Tale of the Muspah quest before Slayer Masters may assign these creatures. The only Slayer masters who can assign Ice strykewyrms are Duradel/Lapalok and Kuradal, with Kuradal assigning them more often than Duradel/Lapalok.

When ice strykewyrms were first released, there was also the restriction that they could only be assigned to players who own a fire cape. However, one month after their release, ice strykewyrms became available to slayers who wished to purchase the ability to fight them by using 2,000 Slayer reward points. Despite this, purchasing the ability does not allow players to kill ice strykewyrms outside of a slayer task; it merely unlocks the ability to be assigned them and to kill them without owning and wearing a fire cape. Because of this, and the fact that most players who have level 93 Slayer will have high enough combat stats to get a fire cape quite easily, it is generally considered a waste of points to purchase this. Nevertheless, it is still an option for players who have particular difficulty in obtaining the fire cape. An update introduced the completionist cape, which can replace the fire cape as an item to kill ice strykewyrms. To obtain it, you will need to have obtained a fire cape at least once, plus other requirements. An update on 28 February 2012 included the ability to use a TokHaar-Kal to damage Ice Strykewyrms.

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. For players not wearing a fire cape, the strykewyrm's maximum hit is slightly increased.

Killing one ice strykewyrm is one of the elite Fremennik Province Tasks. Players who have not completed this elite task are able to make an ice strykewyrm surface even if they are not assigned them as a Slayer task, but this cannot be done using a boosted slayer level. Players without a fire cape will not be able to deal any damage to it whatsoever, including by means of Deflect Curses, Vengeance, rings of recoil, and/or poison. While purchasing the ability to slay ice strykewyrms for 2,000 Slayer reward points is an option, this can only be done by players with at least 93 Slayer for which you cannot use temporary boosts. After killing an ice strykewyrm for the Fremennik Tasks, players will no longer be able to surface an ice strykewyrm without having them assigned as a current slayer task.

Like all strykewyrms, ice strykewyrms reside underground beneath mounds until provoked by a player with the necessary Slayer task. Slayer Masters claim that only those who have been assigned to hunt them may surface the strykewyrms due to the strykewyrm being able to smell the intent of the slayer. By investigating the mounds, the strykewyrm will surface and attack the player. However, the strykewyrm will not attack for about two to three seconds, so players may take advantage of this time to change their position or to get a few good hits in. Players without the necessary task to kill strykewyrms will not be able to surface the strykewyrm and will instead perform the think emote.

Getting there
The ice strykewyrms are located in a cave to the east of room just before the cave in which Jhallan was frozen during The Tale of the Muspah.

The quickest way to get to the ice strykewyrms is to use Fairy ring DKS, which is just south of the cave.

Players can also use the newest Rellekka lodestone and run northeast. Requires activation.

Once inside the cave, the entrance to the ice strykewyrms is the waterfall to the east; if there is water coming through, blocking the way, the player must use a spade to dam the eastern river in cave where the Muspah was frozen. This will stop the water from coming through and allowing the player to use the entrance.

Attack styles
Ice strykewyrms have four types of attacks: melee, magic, freezing spell and burrow. If the player is within one square of a strykewyrm, it will use any of the four attack types. At a distance, the strykewyrm mostly uses its magic attack but will occasionally use its freezing spell (which looks like Ice Barrage), which renders the player unable to move for around three seconds and cancels the player's next attack. Simply clicking the strykewyrm will resume attacking immediately.

The ice strykewyrm's strongest attack is when it burrows underground during battle and then pops back up, dealing up to 2000+ life points to the person it is fighting. There was an update to prevent other players from getting hit by someone else's ice strykewyrm, but it does show an animation of that getting thrown out of the way, but not losing life points. The 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 strykewyrm when it burrows (such as when maging from a distance), the easier it is to avoid this attack. It can also use the burrow attack if a player walks into its square and stays there for a couple of seconds, so it is recommended not to do this. The strykewyrm will not use the burrow attack if the player is standing next to an obstacle, such as the cave wall or a stalagmite. Some players believe moving away from the burrow is easier than trying to stand by an obstacle, while other players believe it is easier to use obstacles.

Strategies
Despite requiring level 93 Slayer, these creatures have low defence and may be killed effectively by several different methods. Ice strykewyrms are weak against fire. Wearing a fire cape increases all damage dealt to a wyrm by 40. Furthermore, all fire spells hit for 1.5x damage, 2x damage if the player is wearing a fire cape. Because they are non-aggressive, there is always opportunity after a kill to use the regenerate ability to heal, the drawback being the extra time that requires. A combination of regeneration, shark drops, Excalibur in the off-hand, the Soul Split prayer or a healing familiar can eliminate the need to bring any food.

In some circumstances, a single magic spell cast may appear as two hit markers simultaneously. This seems to be a side effect of using abilities that score bonus damage. Items that raise the chances of critical hits will make this more common.

Casting ice spells from the Ancient Magicks spellbook will heal the ice strykewyrms instead of damaging them.

A prayer-costlier though safer method is to use Protect from Magic or Deflect Magic, as they stop most damage from the strykewyrm's magic and freezing attacks, although the freezing attack still immobilises the player. When using prayer, players should consider wearing armour with good prayer bonus, such as the dagon'hai robes set.

Trivia

 * Ice strykewyrms, along with the other strykewyrms, were the first monsters to incorporate particle effects.
 * If a player runs behind an obstacle just as a strykewyrm burrows into the ground, the strykewyrm will disappear. Although it will seem to respawn normally, it will leave no drops. This does not count as a kill for the player. This glitch has not been fixed.
 * When attacking an Ice strykewyrm for the Fremennik Province Tasks, the goliath gloves' special effect is able to deal damage to it, making it possible to slay it at level 65 (the minimal requirement to obtain the gloves).
 * When frozen by their magic attack, a block of ice will appear, similar to that of Ice barrage. Fortunately, the freeze does not last long.
 * Despite having a magic-based attack, their magic attack is icicles that they shoot at the player, which would make it as a "ranged" instead of "magic" attack. This might be an oversight from Jagex.
 * When the TokHaar-Kal was given the ability to count as a fire cape when fighting Ice strykewyrms, it did not give the bonus damage effect, and simply allowed players to deal normal damage the same way as the slayer reward. This was later fixed with an update on March 13.
 * When using a steel titan, using scrolls may cause the ice strykewyrm to target your steel titan. This may not be noticeable, and then when it burrows to attack, it seems to disappear. This seems to only happen when using scrolls.
 * If the ice strykewyrm attacks a familiar it will burrow into nothing.
 * If the ice strykewyrm is bound, it will burrow into nothing.
 * This is the only strykewyrm other than the wildywyrm to not drop any of the components for the full slayer helmet. Jungle strykewyrms drop the hexcrest and the desert strykewyrms drop focus sights.
 * The maximum amount of damage a player can deal to an ice strykewyrm in one hit is 10,000 (12,000 with a critical hit).
