Buy OSRS Red spiders' eggs
Red spiders' eggs are a key Herblore ingredient in Old School RuneScape. Players use them to make some of the most useful potions in the game.
At level 22 Herblore, mix red spiders' eggs with a harralander potion (unf) to make a restore potion and earn 62.5 experience. At level 63, add them to a snapdragon potion (unf) to make a super restore potion and earn 142.5 experience. At level 73, combine them with coconut milk and a cactus spine to make weapon poison(+) and earn 190 experience.
There is one more use. Any player can bring red spiders' eggs, a limpwurt root, and 5 coins to the apothecary in Varrock. He will trade them for a 4-dose strength potion.
Red spiders' eggs are tradeable and noteable, but they cannot be equipped or stacked. Each one weighs 0.007 kg. They spawn on the ground in places like Arandar, Edgeville Dungeon, Forthos Dungeon, Varrock Sewers, Pandemonium Cave, and the Crandor and Karamja Dungeon. Gathering them by hand takes time, since each spawn takes 60 seconds to return. Buying them in bulk saves hours for anyone training Herblore.
