I have a level 2 wizard (D&D 5e) with prestidigitation as one of their cantrips and I want to semi-permanently alter my appearance with a silly looking fake moustache, because reasons. I'm unclear about 2 things:
Does a small object created with prestidigitation last for an hour regardless of whether concentration is maintained, or does it last while concentration is maintained only, up to an hour?
Does casting another spell interrupt the prestidigitation effect? Like say I'm in battle, do I have to choose between casting combat spells and maintaining my moustache? Or does it stay put as long as its hour isn't up?
