A cyclops (plural cyclopes) is a monster primarily found on the top floor of the Warriors' Guild, and some can also be found in the Ardougne Zoo and the God Wars Dungeon. They are native to Cyclosis, an island in the Wushanko Isles. In the Warriors' Guild, many players fight them in hopes of getting a defender, as they are the only monsters that drop them besides Cyclossus. Guild Cyclopes come in two varieties: Level 57 (which are bald) and Level 68 (which have hair). They have low defence and a reasonably high number of life points, making them a very good training monster. However, they are completely impervious to ranged and magic. The level 57 cyclopes are the lowest level monster to drop Hard Clue scrolls, although they do not drop them often. Many players bring runes for High Level Alchemy because cyclopes drop Steel, Black, Mithril, and some Adamant items. However, this is not entirely necessary, as the shop on the floor just below them buys all the cyclopes' drops at high alch prices. The cyclopes are also aggressive in the warriors guild making them useful for training, despite the token system. The cyclopes are known to be followers of Bandos.
A Ring of Wealth does not increase the chance of getting a defender. Players may spend anywhere from very few to thousands of tokens before getting defender drops (though it would appear that the Dragon defender drops more frequently than the other defenders).
It is important to note that if you log out while fighting cyclopes, when you log back in you will be outside of the room and have to reselect your choice of token payment.
Cyclopes sometimes summon a Cyclossus in the Warriors Guild. It is a considerable amount more powerful life points-wise, though it only has a max hit of 97. Its special attack knocks the player backwards and stuns them, so it is advisable to be stand against a wall, so that if it does stun you, you can still melee it. A cyclossus will not attack you if you aren't equipped with a rune or dragon defender, and you will not be able to attack it either if that is the case. The chance of encountering a Cyclossus increases if you chose the multi-token option.
On the day of the dragon defender's release, the cyclops room in the Warriors' Guild became extremely crowded by medium to high level players trying to receive one as a drop. Because of the difficulty to find a free cyclops to fight, players threw a throwing knife at one the moment it spawned to be the one that attacked it first and switched to a melee weapon to deal damage to it. This has since been prevented by Jagex and players can no longer range the cyclopes, not even to start a fight.
In the Warriors' Guild, the Cyclopes have varying melee weaknesses. The Cyclopes wielding clubs are weak to stabbing weapons, the Cyclopes wielding hammers are weak to crushing weapons and the Cyclopes that have mohawks or wield cleavers are weak to slashing weapons. It is advisable to target the ones weak to your specific weapon setup to maximise kill rates.
The Cyclopes found in Ardougne Zoo and the God Wars Dungeon are weak to Earth spells.
The level 57 and 68 cyclopes may be found in the Warriors' Guild. To get inside the Warriors' Guild, a player's Attack and Strength levels must add up to a sum of 130 or greater, or either of these stats can be level 99. In order to enter the Cyclops area, located on the third floor, a player must gain at least 200 Warrior guild tokens. 20 tokens are no longer used up immediately upon entering the room, but 20 are still depleted every minute. The player must leave when the tokens run out, and will be forced out if they do not do so.
Level 91 cyclopes inhabit the God Wars Dungeon in the Bandos' stronghold, and therefore require 70 Strength to access. These cyclopes do not drop defenders.
There is also a level 63 Cyclops in the Ardougne Zoo. This cyclops does not drop defenders.
