Elemental staves provide an infinite amount of one or two of the basic elemental runes: air, water, earth, and fire. The staves come in three different types:
Basic elemental staves have no requirements to wield and can be bought from various stores.
Battlestaves require 30 Magic and Attack to wield, and can be created by adding an orb, created through Crafting and charged through Magic to a regular battlestaff. Battlestaves that provide an infinite amount of two runes cannot be created, only obtained through monster drops.
Mystic staves require 40 Magic and Attack to wield, and can be created by paying Thormac 40,000 coins and giving him a charged battlestaff after a player has completed the Scorpion Catcher quest.
Requires 240 Telekinetic, 240 Alchemist, 2400 Enchantment and 240 Graveyard points, and a teacher wand equipped or in the player's inventory, to purchase from the Mage Training Arena. Thus it does not cost much besides the time and runes spent in the Mage Training Arena.
Has a special attack that halves all melee damage the player takes for one minute, which stacks with the PvP damage reduction effect of the Protect from Melee prayer. This consumes 100% of the player's special attack.
When a combat spell is cast with the staff, there is a 1/8 (12.5%) chance that the staff will negate the rune cost for that spell.
Currently the strongest staff when used as a melee weapon, surpassing the Ancient staff and Iban's staff, and provides +17 magic defence.
