Dust devil

The Dust Devil is a very popular monster for Slayers of level 65 and up. A Face mask, Masked earmuffs, or Slayer helmet is always required to slay them, whether in the Smoke Dungeon or Chaos Tunnels, because of their effects on players without protection. (The Slayer helmet also has the same benefits as the Black mask when the dust devil is your current slayer assignment.)

Dust devils are vulnerable to Ranged attacks. Dust devils drop the coveted Dragon chainbody, although it is an extremely rare drop. Dust Devils are also known for their high drop rate of crimson charms and are hunted by players looking for fast Summoning experience. They drop charms in a rate of ~40% and the crimson charms make a half of them.

Players may consider using the low graphics detail setting when fighting Dust Devils, as this will reduce the visual effects of their dust.

Locations

 * Smoke Dungeon west from Pollnivneach in the Kharidian Desert.
 * Chaos Tunnels

Strengths and weaknesses
Dust Devils attack with melee type damage, at close range. Their dusty, gritty attack, even if it causes no damage to hitpoints, has the special effect of greatly reducing an unprotected player's combat skill levels. A single attack can reduce attack, strength, ranged, and magic to 0 while halving prayer. A Facemask, Slayer helmet, or Masked earmuffs completely protects the player from the dust devil's special effect.

Players need at least level 65 Slayer to fight these creatures. The protective facemask, slayer helmet, or masked earmuffs are also required just to survive in the Smoke Dungeon, one of the dust devil's habitats. In the Chaos Tunnels, their other habitat, the protective equipment is only required when fighting the devils themselves.

The Smoke Dungeon has many safe spots where players can use ranged, magic or halberds to defeat them.

Melee is also effective, a good strategy for which is using the spell Bones to Peaches to maximise one's stay in the dungeon. It is possible to use Guthans armour to heal, although players must be careful switching the helm with the face mask, otherwise the dungeon will hit them for 20 damage every 12 seconds or so, only allowing 3-4 hits in before having to switch back to the face mask. Please note that you can only use Guthan's armour to heal on nearby Fire Elementals, Pyrefiends, or Fire Giants, as attacking a Dust Devil without a face mask causes your attack, strength, defence, range, and magic stats to be drained to 0, and deals 15 damage to you every few seconds. So Bones to Peaches would be the best method to use.

If the player chooses to use the Chaos Tunnels instead, he/she will still need the facemask to kill the Dust Devils themselves, but since there's no environmental smoke, Guthan's can be used to heal on the Giant Crypt Rats in the next cave to the east.

Another great method is to use the special of the Saradomin Godsword which will keep a higher level character at a fairly good amount of hitpoints. This along with the melee protect prayer at full prayer can keep you there for an extraordinary amount of time. Players should also bring super sets if they are on a slayer task and want to finish it quickly.

Trivia

 * The "Dust Devil" is a model of vacuum cleaner hence the examine text.
 * Although they drop bones, dust devils do not appear to have bones, as they are supposedly filled with air. They may have a skull of some sort, however.
 * Lots of their drops are the colour of dragon metal (Crimson charm, Red d'hide vambraces, Uncut ruby) which could be a joke by Jagex, making a player think they have received a Dragon Chainbody.
 * Smoke Devils are the summoning counterpart of the dust devil.
 * In the American Midwest dust devils are a miniature whirlwind strong enough to whip dust, leaves, and litter into the air.
