Jungle strykewyrm

Jungle strykewyrms are slayer monsters that are located directly north of Mobilising Armies, next to the three fishing spots along the western coast. They are some of the most visually striking creatures in RuneScape, but you may only fight these creatures if you have 73+ Slayer and have them assigned as a task by a Slayer Master.

Attacks
Jungle strykewyrms don't hit very high with their normal melee and magic-based attacks, but they have a special attack where they tunnel under your feet, then push you back from beneath. This attack hits 300 and can poison you for 40-80 (you can avoid this attack easily by running away as soon as it starts tunneling).

It has 4 attack types:
 * 1) A fairly weak and inaccurate melee attack (up to 87 life points), which can poison through prayer.
 * 2) A special attack when the wyrm buries itself into the ground and then bursts out with tremendous force, hitting 300 + poison. This attack can be avoided by running away. Standing with your back against a solid object such as a rock or a tree prevents the strykewyrm using this attack.(This attack can be completely avoided by standing next to an obstacle, such as rocks. This is highly recommended.)
 * 3) A magic attack that looks like a large purple ball which explodes upon impact.
 * 4) A rarer magic cloud-like attack that can poison, dealing 40-80 life points.

Given the number of poison attacks these creatures possess, It is highly advised that you bring Super antipoison potions when doing this task. If you have high Defence and have completed The Great Brain Robbery then a prayer book and holy symbol can substitute nicely. Another option for players with 60 Defence, 60 Dungeoneering, and 70 Herblore is to equip an Anti-poison totem, which provides full immunity to poison along with fairly decent defensive bonuses, but disallows the use of two-handed weapons, such as Godswords.

An alternative is to summon a Unicorn Stallion and use its 'Cure' Ability to remove the poison in addition to its Healing Aura scrolls. Once a player runs out of Summoning points, they may recharge it by taking Spirit Tree transportation to Grand Tree and then using the nearby mini-obelisk there, or by using the mini-obelisk just west of Oo'glog.

Weaknesses
Jungle strykewyrms are generally weak against stab and ranged attacks, but they are immune to leaf-bladed swords. It is unknown whether this is intentional, due to the n ture reference in the sword's name, or a glitch. They are also immune to poison (as shown by Monster Examine), due to their poisonous nature.

Once the strykewyrms spawn to the surface, whether after a special attack or an investigation, the wyrm will not attack for a few seconds. This gives you the opportunity to attack it (preferably a fast hitting weapon or the special of the Dragon Dagger) without retaliation. When asked for tips, Sumona notes that they are inherently passive creatures, who become aggressive upon sensing the slayer's own ill intent.

Since they attack with melee most of the time, melee armour is suggested for killing them, but players with 80+ Defence can be productive with black dragonhide armour or better and a rune kiteshield or better. A combination of black d'hide legs and the rest a strength bonus outfit can be very effective for slayer with stats around 80. Potting up attack and strength can increase your stay times and make the tasks and kill go faster, eliminating extra damage that may occur from slower kills. Do not bring Super Defence potions since they are dropped at a sufficient rate to keep you fully supplied.

In the past, a player could step on the jungle strykewym so that it would not be able to attack the player.

Trivia

 * Jungle strykewyrms, along with the rest of the strykewyrms, are the first monsters in RuneScape that make use of particle Effects.
 * The special attack of the strykewyrm (bursting out of the ground and hitting for 300 life points) will affect all players in its path. The attack cannot be recoiled by Vengeance.
 * The special attack can also be activated if one stands on any strykewyrm whilst it is above ground.
 * The special can occasionally hit twice consecutively hitting up to 600 life points instantly, although it is unknown if this was intentional. Although rare for this to happen, slayers should keep their life points above 600 to avoid an accidental death.
 * The release of strykewyrms was hinted at by the Chaos Elemental in the Postbag a few weeks earlier and by the Twitter Clue "Three strykes and they're out" which is a pun on the baseball term Three strikes and you're out!. The Twitter Clue was also posted on Facebook.
 * As of 11 February, 2010, Jungle strykewyrms can be assigned by Kuradal, Duradel, Lapalok (with While Guthix Sleeps complete), Chaeldar, and Sumona.
