Some other players of 5e D&D have suggested that the Clone spell only works with a Medium size body. Putting this into perspective (and putting aside obvious yet possibly reasonable discrimination against creatures such as gnomes, kobolds and halflings), what is the actual RAW on this?
Question: What living creatures can be cloned by the 8th level Clone spell – from what micro-minimum to what absolute maximum in size could this thing be?
Best Answer
A creature can be cloned; the 'medium' size looks like a limitation
Clone's spell description says this:
And, it says this.
But the 2018 errata says this:
And who wants to clone gnomes, anyway? 8^p
Korvin's ruling as a DM?
I'd let a halfling or gnome PC have a clone; it would fit - but only if they player bought pizza for the next session! 8^D
Something that might work ...
If you cast the second level spell enlarge/reduce on the creature in question, and then use wish to cast clone (which avoids the need for spell components) you can probably make it work for a Small or Large creature.
As for what size the clone ends up being - that could be an interesting surprise. (thanks to @ RedOrca)
