You create a field of magical instability that tends to disrupt magical effects. Any creature within that field receives a bonus equal to your level to their saving throws to avoid a magical effect. Magical attacks that target a creature within the field suffer a penalty equal to your level to their spell attack rolls. This includes spells that target multiple creatures, if any of its targets are within the ward.
