The description of the Mage of Lorehold's Ancient Companion feature (from UA: Mages of Strixhaven) reads, in part:
Whenever you finish a short or long rest, you can call forth and bond with one such spirit, who comes to inhabit a Medium, freestanding statue within 10 feet of you to serve as your ancient companion.
What are the ways by which I can reduce the size of my Ancient Companion, either temporarily or (preferably) permanently?
Ideas I've come up with so far:
- Cast Enlarge/Reduce on it
- Use Wish (the risky way) to cast Enlarge/Reduce on it, making the size change permanent
- Have it drink a Potion of Diminution
- Have it drink a Potion of Diminution together with another potion which gives a 1% chance to make the effect permanent (source)
Ideally I would like my Ancient Companion to be able to attune to a magic item that just shrinks it by one or two size categories, but I haven't found anything suitable so far...
