Stun

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

This type of spell is commonly used with a Mud Staff because the staff provides an infinite amount of earth and water runes, thus requiring only one soul rune per cast.

Wise players may cast this spell on the Lumbridge training dummies because this provides the fastest Magic experience for its affordable price. Wearing sacred clay armour cuts the cost by half, since it gives the player double experience. While wielding a Mud Staff, the price for casting this spell is coins (the current price of a single soul rune). At 180 experience with sacred clay armour, you would be getting 1 Magic experience per coins. In most cases, this is more affordable than high alching, and at almost 3x the speed, it should be considered an excellent option for training Magic. Alternatively, if a player wishes to minimize losses, some items may be alchemised with little or no loss. However, due to price fluctuations, this list of items is always changing. For more information, see Calculators/High alchemy.

A player can gain about 200,000 Magic experience an hour without moving the mouse whatsoever. To do so, the player must utilize sacred clay armour and cast stun on the training dummies at the Combat Tutors in Lumbridge. Full screen mode and mouse keys are also needed. With mouse keys turned on, the #5 key will be the mouse's left-click button, and F4 will open or close the spellbook. The player should position the mouse pointer over stun (or another spell of choice) and rotate the screen until the mouse is hovering over a dummy. Then, the player can continue to click F4 to open the book, 5 to click stun, F4 to close, 5 to click the dummy, and repeat.

A friendly recommendation is to bring 10-100 extra law runes. These can be used to temporarily "stun" botting players via a teleother spell. If the receiving player has the assist option on, these spells cause an interface screen to pop up, asking them if they wish to teleport to the destination in which you cast. Although these spells give similar exp to the stun spell, they will cost you an extra law rune, but by "stunning" botting players, you are then able to "steal" their dummy, as well as render their bot useless as only one player may attack a dummy at a time.

Players can be frequently found casting this spell across the wilderness ditch north of Edgeville, but this is less efficient than the mouse keys method at the Lumbridge dummies. If you DO decide to do this with the wilderness ditch or anywhere else with something in between you and your enemy, it is highly recommended to use armour that lowers your magic attack bonus (melee armour, range armour). With lower magic attack bonuses, the spell will splash more often, allowing you to continue splashing the same monster.

Stun costs coins for each cast, or  coins if a Mystic mud staff or Mud battlestaff is equipped.

Remember, you cannot use Ancient Magicks or Lunar Spells if you are using regular Magic.
