Wind Rush, a free-to-play magic spell, was the weakest wind spell in the standard spellbook and the game. This spell could deal a maximum damage of 10 without boosts. This spell required no catalytic runes. An air elemental staff could be used to cast it for free. Like all combat spells, each damage point caused by this spell yielded 0.2 magic experience and 0.133 constitution experience. It was removed from the game when the Evolution of Combat was launched on 20 November 2012.
This was one of the few attack methods that could damage Salarin the Twisted. When used against him, the spell would either "splash" or damage him for 90 life points.
Wind rush was very popular for new players and was seen being used mainly around areas populated by new players, such as Lumbridge. It was attractive because it only required level 1 magic to cast, and there were no runes needed if a staff of air was equipped. However, for players with a magic level 5 or above, a warning message would appear, advising them not to use this spell due to its low maximum damage.
Wind rush also had its uses for experienced players. It was often used in crowded, single combat areas such as green dragon spawns in order to quickly engage in combat with the monster. The player could continue fighting the monster using melee without the risk of another player getting the chance to strike first. This worked well because it was inexpensive to cast and took up only one inventory space. When the inventory was filling up, any excess runes could be dropped at minimal cost to make room for more expensive monster drops.

- Wind Rush was the only combat spell that could not be cast against other players. This was because it yields magic experience even when it fails to hit the target, where players can abuse such advantage to level up magic easily whilst away from keyboard.
