Ancient Zygomites are stronger variants of mutated zygomites that require level 57 Slayer to harm. They are found exclusively on Fossil Island in the Mushroom Forest. Ancient zygomites cannot be killed unless a fungicide spray has been used to deliver the final blow. They first appear as non-attackable Ancient Fungi, which players must pick in order to provoke them out of the ground. Players who have been given a mutated zygomite Slayer assignment can choose to kill them as an alternative for the task.

Strengths and weaknesses

Ancient Fungi

Ancient Zygomites use both magic-based melee attacks and magic-based ranged. Armour with a low magic defence bonus such as rune will typically have a higher chance of being hit, therefore dragonhide armour is strongly recommended while fighting them, as its higher magic defence will reduce the chance of being damaged. If praying against their attacks, Protect from Missiles is recommended, as their ranged attacks are stronger and more accurate than their melee attacks.
