The Guardian Portrait states that it can innately cast a variety of spells.
The description of its innate ability specifies it needs no material components.
The portrait can innately cast the following spells, requiring no material components: 3/day each: counterspell, crown of madness, hypnotic pattern, telekinesis
False Appearance. While the figure in the portrait remains motionless, the portrait is indistinguishable from a normal painting.
Is it a general rule that innately case spells don’t need material components - or is the exception for material components always listed if possible? Do innately cast spells always need the somatic and verbal components of the original spells unless noted?
