D&D 5E Returning Weapon + Enhanced Weapon?

[TrueBagelMan]

TL;DR does Returning Weapon and Enhanced Weapon stack?



So I was looking through Artificer since one of my players wants to play one. I saw that one weapon could have returning weapon and enhanced weapon on the same one. My question is do the +1s stack? I don’t see any rules saying anything about this. If they do stack and the player finds this it would be interesting since they would have a thrown weapon(Trident for example) so they can have a transforming cutlass that becomes a flintlock pistol. So 1d8+INT+2 magical piercing damage at level 3.

It's in the general artificer rules that you can only have one infusion per item, so you can't have both Enhanced and Returning on the same weapon. Nor can you put an infusion on an already magical item. So they can never stack.
