Wind Rush

Wind Rush is a very weak air spell that requires level 1 Magic and 2 air runes to cast, but cannot be used on other players.

This spell was created to allow low level players to train magic for free, as more wealthy players can choose Wind Strike as an alternative, as it requires the same Magic level, but deals much higher damage albeit at a higher cost.

When cast, the missile looks like a smaller version of Wind Strike, but the smaller version is exclusive to Wind Rush, as there are no other elemental Rush spells as of now.

Wind Rush costs coins for each cast, which is reduced to 0 coins when an air supplying staff is wielded.

Usage
Wind Rush is very popular for new players, and it is seen used mainly around areas that contain new players, such as Lumbridge. New players are attracted to Wind Rush because (as stated earlier) it only requires level 1 Magic to cast, and there are no runes needed if a Staff of Air is equipped.

Nonetheless, Wind Rush still has its uses for experienced players; it is often used in crowded, non-multicombat areas such as Green Dragon spots for attracting the attention of monsters, so that they can continue fighting the monster with melee without risk of another player getting the chance to strike first. This works well, as it is so cheap to cast and takes up only 1 inventory slot. Any excess runes left after an inventory is filled can be dropped at minimal cost.
