None of your offerings are of any particular interest to these creatures,
who are much more interested in you than your gifts.
You try to impress them with an Illusion Spell,
creating a colourful rainbow across the centre of the room.
They are fascinated and allow you to pass through to the far door.
If you do not have an Illusion Spell, you must use one of your other Spells to impress them.
If you have no other Spells, you must approach them.
