Cockatrice are Slayer monsters that require level 25 Slayer to kill. They frequently drop limpwurt roots, which are their main food source and used in the Herblore skill, and rarely drop the Cockatrice head, which can be brought to the Taxidermist in Canifis and stuffed for 2,000 gp. Wearing the Mask of Stone doubles the drop rate.

In the quest Fur 'n Seek, cockatrice skin must be collected and cleaned for the Odd Old Man.

Protective equipment

Equipment is necessary to avoid the stat-draining attack of the cockatrice. Any of the following can be used:

• Mirror shield
• Mask of Stone / Helm of Petrification
• Mask of Reflection / Helm of Little Kings
• Sunglasses

The Slayer helmet does not defend against this attack.

Players without level 20 Defence will not be assigned a cockatrice Slayer assignment. Once per day, players can force a cockatrice Slayer assignment by talking to Mazchna whilst wearing the Mask of Stone or Helm of Petrification.

Strengths and weaknesses

Cockatrices in the Fremennik Slayer Dungeon.

Cockatrice have a special stat-draining attack, which they use if the player is not wearing protective equipment. It will shoot out beams from its eyes, quickly reducing Attack, Strength, Defence, Ranged, Magic, Agility, and Summoning to dangerously low levels (1/4 of the player's original levels, e.g. 15/60) and causes rapid damage for up to 110 life points per hit (it does more damage with higher levels). These beams always hit a fixed amount. This is why a mirror shield is necessary. Use a restore or super restore potion to recover from these effects.

If the player is protected, however, they fight using standard melee and ranged attacks. They have few life points and do not hit substantially. Their attack speed is the same as a scimitar or mace. They are weak against crush attacks, although any melee weapon will suffice.
