Step 1: Enter Jormungand's Prison with Mirror shield or V's shield equipped. Without it, their gaze attack will drastically reduce your accuracy, making kills near impossible.
Step 2: Activate Protect from Magic if you wish to AFK or minimise food consumption, especially with mid-level Defence.
Step 3: Focus on maintaining your buffs with Super combat potions for optimal DPS. Their max hit is 22 but with Protect from Melee or V's shield, damage is minimal.
Step 4: Keep an eye out for Basilisk jaw drops (1/5,000 chance), which can be attached to your Neitiznot helmet to create the Neitiznot faceguard, providing extra Strength and defensive bonuses and increasing your total DPS for all melee tasks.
There are multiple safe spots inside the Island of the Stone dungeon, such as:


This is a method by which many choose the option of using ranged and attacking them from afar so that basilisk knights can only hit them with magic and use prayer magic, not receiving any hits which makes it a more AFK method. You just have to be aware of the prayer.
