Basilisk

A Basilisk is a Slayer monster that requires a Slayer level of 40 to kill. Players must equip a mirror shield when fighting these monsters or have their stats dangerously reduced by the Basilisk's stare. In addition to stats being drained, they will constantly hit 11's on you without a miss. Basilisks attack with melee, so wearing good melee armour will ensure that the player takes minimal damage. Shortly after the release of Summoning, the Fremennik Slayer Dungeon was almost always inundated with people seeking charms from the Basilisks. This area is not nearly as crowded these days, but it can still get quite busy at peak times.

Players with level 70 defence or above will not get hit very often, so less food is recommended to make room for drops. The spell Bones to peaches is highly recommended for lower levels or mage "pures". It is also possible to safe spot them from the south in the Fremennik Slayer Dungeon if you hug the eastern wall near the south entrance. (NOTE: You still need a mirror shield even if you kill Basilisks from a safe spot.)

A player can obtain a baby basilisk as a pet, by taking a rare Basilisk head (stuffed or unstuffed) to Nomad in the Soul Wars lobby. Turning the head into the pet costs 40 zeal points. A Ring of Wealth appears to increase the drop rate of the head.

Trivia

 * In the Fremennik Slayer Dungeon there was a crevice that basilisks walked over and appeared to float above the ground, this has now been fixed.
 * When they attack, their rear right foot used to pivot on the floor unrealistically. This has now been fixed.
