For melee combat,it's crucial to maximize both your offensive and defensive stats. The best gear for RuneScape gold melee would include the highest-level platebody and platelegs/plateskirt you can afford,such as Rune,Dragon,or Adamant. These will significantly improve your defensive capabilities.

In terms of weapons,the Abyssal whip is an excellent choice due to its high attack speed and strength bonus. For those who haven't unlocked the whip yet,the Dragon Scimitar is a great alternative that offers a good balance of speed and damage. Additionally,equipping a Dragon defender can further boost your attack and defense stats,making it a powerful combination when fighting Cockatrices. 

Don't forget to wear your mirror shield in your shield slot,as it's essential for protecting yourself from their petrifying gaze. If you don't have the Fire cape yet,the Obsidian cape or the Ardougne cape are good substitutes.
Equipment for Magic

For magic users,your gear should enhance both your magical accuracy and damage output. A basic option would be the Mystic set,which provides a nice boost to your magic attack stats without costing too much. For higher-level mages,the Ahrim's set from the Barrows minigame can significantly increase your magic strength,making your spells much more powerful.

The Staff of Air is a good choice for those looking to save on rune costs for Air spells,and it pairs well with your spellbook. For players who want to conserve runes,the Slayer's Staff (e) is a useful option for casting Slayer Dart at a reduced rune cost. 

For those with higher levels of magic,the Trident of the Seas or Trident of the Swamp is are excellent choice due to their high damage output and fast casting speed. As with other combat styles,don't forget to equip your mirror shield to protect against the Cockatrice's petrifying gaze.
Final Considerations

Whether you're after mystic boots,clue scrolls,or simply looking to buy RS gold improve your Slayer experience,Cockatrices are a great monster to tackle early on. With the proper preparation,these petrifying creatures will become a consistent and rewarding task in your Slayer log.
