Mass Interference is the mass attack version of Interference. As such, it can affect multiple targets in a room rather than a single target.

Mass Interference is an autosuccess spell and will automatically succeed when cast on a target no more than 10 levels above the caster. Against a bounty boss or ascension creature, it can succeed up to 20 levels above, with a 10% failure chance per level difference over 10. Failing due to the failure chance will grant a stacking 20% decrease to the failure chance on subsequent casts.

Mana Control Benefit

Potential targets for most open cast spells are set at a base maximum of 3, with additional targets possible for each 50 skill bonus of the appropriate mana control for this spell.
