Stun

Stun is a spell that temporarily reduces your opponent's Attack level by 10%. However, if this spell is successfully cast, it may not be cast again upon the same target until its effects have worn off.

This type of spell is commonly used with a Mud battlestaff or a Mystic mud staff because the staff provides an infinite amount of earth and water runes, thus requiring only one soul rune per cast. With a Mud staff, players may receive 1 Magic experience for approximately coins, or about  coins if using sacred clay armour. This is oftentimes more affordable than casting high alchemy, and takes a much smaller cash investment (no need to buy items to alch).

Players may also choose to use an earth staff along with a tome of frost. This combination of equipment is the cheaper equivalent to the mud battlestaff.

Players used to cast this spell on the Lumbridge dummies, utilising mouse keys and some using sacred clay armour to gain up to 200K experience an hour. However, an update rendered this method obsolete as the dummies may now only be used by low-levelled players. This caused some anger amongst players as this was a very efficient method to train magic, and many people had invested a lot of time and money in getting soul runes and/or sacred clay armour.

Players can be frequently found casting this spell across the Wilderness Wall north of Edgeville or at the Monk of Zamorak beneath the stairs of Varrock Palace. If casting stun there, or anywhere else with an obstacle, players are highly recommended to use armour that lowers their magic attack bonuses (melee armour, range armour). With low magic attack bonuses, the spell will splash more often, allowing players to continuously "splash" on the same monster. If the player can get at least a -65 magic attack bonus, they will always splash. This can be achieved with metal boots, full melee armour and any type of vambrace other than leatheer.

Good negative magic bonus armour includes any metal full helm, platebody, platelegs or plateskirt, granite or obsidian shield, any dragonhide vambraces, and snakeskin boots. Sacred clay melee armour can replace the full helm, platebody, and leg armour, while giving double experience while it has charge; the only downside is that the player must spend time playing Stealing Creation.

The best places to stun are:

-Wilderness ditch, Varrock Palace (bear cage), Varrock Palace (Monk of zamorak) -There's a lot more good places to stun but the ones listed above are the most popular.some people can alter the screen so that they can use mousekeys.

Though stunning is fair Magic experience, most people choose not to stun and use High Level Alchemy due to the update to the Lumbridge dummies, making them unstunnable.

It costs approximately 8.5 million coins to get 94 Magic (for Ice Barrage) from Stun while wielding a mud staff and at least one piece of stealing creation armour. (80-94 mage = 33104 casts, with stealing creation armour. 33104*258= 8,540,832)

Stun costs 0 coins to cast or coins if a Mystic mud staff, Mud battlestaff, or a Staff of earth in conjunction with a Tome of frost is equipped.
