You can cast a spell so that it becomes invisible, inaudible, or appear as another spell entirely.
Benefit: A spell affected by this feat has no visual or auditory effects or has the visual and auditory effects of your choice (as per major image); spells based on light or sound (such as prismatic spray or shout) have no effect when modified by this feat. Certain other conditions can render the spell detectable (such as destruction of objects or disturbing a puddle). Opponents who succeed on a disbelief check (Will save DC 10+ level of spell + primary casting ability modifier) or a Perception check (DC 30) can discern what has happened. A misleading spell uses up a spell slot four levels higher than the spell’s actual level.
