Glod is immune to poison-based attacks. In addition, he also has the ability to disable any active Prayers on the player, also lowering their prayer points by a noticeable amount. However, this does not work like a Dragon scimitar's special attack, which prevents players from using protection prayers for five seconds. If you stand at least 3 steps away from him, he will not be able to use his melee attacks. Alternatively, using melee with Protect from Melee will negate damage from his attacks. He can be fought in the Nightmare Zone after the quest is complete.
