The Earth obelisk is used to cast the Charge Earth Orb spell. The spell is cast on the obelisk in order to charge an unpowered orb into an earth orb. The Obelisk is located in the Wilderness area of Edgeville Dungeon.
When using this obelisk it's best to bring methods to combat poison, such as a Prayer book (available during and after The Great Brain Robbery, not to be confused with a God book) and Holy symbol) to cure poison, the Anti-poison totem to prevent being poisoned, or the poison purge aura to heal you by what the poison should have damaged, as the poison spiders can poison you even if you have Protect from Melee prayer on. Using the prayer book is not recommended as the player would be repeatedly poisoned again, and suffer heavy prayer drain. Poison purge auras is possibly the best method, as it has no requirements, is bought with freely obtained Loyalty points, and also helps healing damage that the spiders or other creatures could deal. However, it has a short time limit. The anti-poison totem requires 60 Defence, 60 Dungeoneering and 70 Herblore to equip, and cost 44,000 Dungeoneering tokens from the Rewards trader, but has no limit to its use.
You used to be able to safe spot at the obelisk, but has since been removed. You may be attacked by poison spiders when charging orbs.
