I'm currently playing as an artificer. I know that when an artificer imbues one of their infusions into an item, it makes a non-magic item into a semi-magic item.
Say I imbue the Enhanced Weapon artificer infusion into a staff, and then my party's druid casts the shillelagh cantrip on the same staff.
Would the effects of Enhanced Weapon stack with those of shillelagh? Or would this negate the infusion, or otherwise not work as intended?
Best Answer
Yes, it's legal (...if it's the Druid holding the staff or club)
The description of infusing an item says:
It clearly points out that the object must be non-magical to start and becomes magical after the process. So the Artificer makes a magical staff.
Now the Druid comes along and casts Shillelagh:
The spell calls out that the weapon can be magical. No magical "plus" bonuses to worry about stacking.
The spell changes the attack and damage rolls from Strength to Wisdom and updating the damage die. Nothing in the description would indicate it would cancel out the infusion; it doesn't care.
It also shows that the spell only lasts while the Druid is holding the weapon. Your phrasing didn't make it clear that the Druid would maintain control of the staff after infusion, so I wanted to point this out. I don't want you to assume that the Artificer could hold the staff and the Druid cast Shillelagh and it would still work.
