Smoke Rush is the weakest of the smoke spells and the weakest combat spell in the Ancient Magicks spellbook. This spell requires a Magic level of 50 to cast and can reduce the target's chance to hit by 5% for ten seconds. It has a guaranteed chance to reduce the target's hit chance when cast as an auto-attack. If this spell is used with an ability, it only has a 10% chance to reduce hit chance or a 20% chance if the caster has Dark Form active. It requires a death rune and three air runes to cast. The base damage of this spell is 480, and it scales up to 576 at level 60 Magic.

As with all Ancient Magicks spells, the quest Desert Treasure must be completed to cast this spell.
