Warped tortoise

The Warped tortoise is found in the Poison Waste Slayer Dungeon during the The Path of Glouphrie quest and can be fought there during and after the quest.

About the creature
These creatures are naturally invincible, as in, in their normal state they cannot be harmed by any means. In order for players to damage and ultimately defeat a warped tortoise, they must posses the crystal chime in their inventory; this effect will be triggered automatically as the player attacks the creatures. To tell if the creature has become vulnerable, note that the shell of a "cleansed" (and therefore vulnerable) tortoise is a darker shade than that of an "uncleansed" one. Once "cleansed" by the effect of the crystal chime, these monsters become vulnerable to all types of attack. Slash attacks are the most effective form of melee attack against these creatures. These creatures are capable of hitting up to 106 lifepoints damage.

These creatures are an environmental hazard during the quest The path of Glouphrie. After the quest, players may be assigned to kill these creatures as a slayer assignment. Although this may sound fairly intimidating to players with bad memories of this section of the quest, several of these creatures can be found at the entrance to the dungeon where players will not need to worry about interference from the large number of warped terrorbirds found deeper into the dungeon. However this room can get fairly busy as players kill these monsters both in order to complete their slayer tasks as well as drop hunters after either shells or cash. Much deeper into the area, the room directly before the large room where the boss fight and conclusion of the quest took place, also houses a slightly larger number of tortoises, and is free of terrorbirds. Using this room could easily speed up a slayer task, but will be much more unwieldy as the player will have to navigate the entire sewer system and fend off attacks from the multitude of creatures in between these two rooms. Both rooms are multicombat.

Chime Update
An update in early March 2010 made the crystal chime's function automatic. Warped tortoises are now automatically chimed while being attacked. Originally players had to manually chime each creature before (and sometimes during) the battle. Manual chiming is no longer necessary unless using mass attack methods such as Ancient Magicks or the dwarf multi-cannon. This update was greatly appreciated by players, and is regarded as making these creatures considerably easier to deal with.

Drop tips
These creatures occasionally drop tortoise shells, the highly sought after tertiary ingredient used used to create War Tortoise Pouches with the Summoning skill. These can be worth a good deal and make the Warped Tortoise a viable money making option. Note that the similar drop Perfect shell has no relation to summoning, and cannot be used interchangeably while summoning. Perfect shells are instead sold to the goblin Barlak in the city of Dorgesh-Kaan, for which he gives the player 500 Crafting experience and 600 coins.

Warped Tortoises commonly drop tangled toads' legs which heal 150 life points. Players may want to consider limiting the amount of food they bring in anticipation of this in order to maximise the number of drops they can obtain per trip.

Fighting Tips

 * Multi-way combat area: The Poison Waste Slayer Dungeon, where this creature can be found, is a multi-combat area. If a player decides to use mass combat methods, such as a Dwarf multicannon, or the ancient magicks, only cleansed tortoises will receive damage . Hitting uncleansed tortoises via this method can be a nuisance, and in some cases can become fairly hazardous as invincible tortoises will begin attacking the player. Use these methods cautiously.


 * Note : Despite living in an apparently poisonous environment, warped tortoises  can be poisoned and will continue to be harmed by poison even after it has reverted to its uncleansed state.


 * For Experienced Players: Players with a high Defence or access to the bunyip summoning familiar should bring little to no food in order to maximize the number of item drops they can pick up. Enhanced Excalibur is highly recommended for usage here, for players with access to it. Players may also use Bones to Peaches in order to stay for extended periods of time.


 * Safe spotting: Players with a low Defence can safely attack these creatures using Ranged, Magic, or a Halberd just south of the gap in the very first room. The two eastern corners are safe spots as well. Safe spotting is a good tactic to consider based on current player needs and circumstances, but is often considerably slower than face-to-face combat.


 * Prayer: Prayer is surprisingly easy to use sustainably against these creatures, and are useful in the obvious ways. Prayers and Curses such as Piety or Turmoil, and Deflect or Protect from Melee can be used without a need for prayer potions . This can be done by using the ability of any version of the Ardougne cloak, which is received from completing any difficulty of the Ardougne achievement diary, to teleport directly to the Kandarin Monastery. Players can recharge their Prayer here, which is only a short run to the Spirit Tree located at Khazard Battlefield, which can be used to quickly return to the Poison Waste Dungeon and continue fighting. The entire process should take under a minute, including running back to the dungeon entrance.


 * Location and Transit: Although not obvious at first glance it is very easy to reach a bank from the dungeon. Using the nearby Spirit Tree to reach areas such as the Grand Exchange or Mobilising Armies puts players almost in the lap of various banks. If the player has an active a follower out and thus cannot access the Grand Exchange, they are recommended to travel to the Tree Gnome Stronghold, where an obelisk can be found mere steps from the tree, with the bank near the magic tree and yew tree groves only a small distance further away.


 * Entrance Room: It should be noted that in the entrance room where there are two Warped Tortoises it is common to find players who will refuse to share the space, despite the fast spawn rate of the Tortoises (after time for picking up drops/burying bones one need only wait around 2 seconds before the Tortoise respawns. Players will regularly attempt to steal your kill if they are on a Slayer assignment or have a higher combat level than you as this is a multi-way combat area.

Trivia

 * At one time it was possible to heal using Guthan's set even when the tortoises were not made vulnerable by the crystal chimes. This was because at one point Guthan's set counted potential damage inflicted on foes even when actual damage was not possible due to prayer or other invulnerability. An update on 9 June 2009 fixed this bug.
 * When examining a warped tortoise, the message says, "You don't think you can harm this creature." However, if you examine a Warped Terrorbird, the message says, "You don't think you can harm this terrorbird," referring specifically to the terrorbird.
