Red spiders' eggs

Red spiders' eggs can be obtained as a drop from Poison spiders, located in the Barbarian dungeon and as a drop from Deadly red spiders, located in Karamja dungeon. The fastest way to obtain this ingredient is by killing the deadly red spiders because they always drop the red spiders' eggs.

Super restore potions are created by using the red spiders' eggs on an Unfinished snapdragon potion. This requires a herblore level of 74 and will grant 715 experience.
