I have now swapped out mage hand for prestidigitation for roleplaying reasons and will grab mage hand at 4th instead. I feel Mage Hand is more mechanically useful but all your great comments have convinced me that thematically Prestidigitation is the way for while I'm at 3rd.
I have six or seven weeks before we start this campaign with her so will probably keep swapping things around for awhile.
She has Vicious Mockery and Prestidigitation
Being a debilitator she also has Bane which I think I have a pretty good chance of landing on an enemy or three due to the Charisma save. This will mix well with Cutting Words and VM for Debuffing.
Healing Word, Disguise Self (a Tabaxi will stand out) and Thunderwave to clear away unwanted attention.
For 2nd level spells I have gone with Invisibility and Suggestion.
I am aware that Prestidigitation, Disguise Self, Invisibility and Suggestion have limited combat usefulness and are more for the social/exploration sides of things which I am going to enjoy.
Do folks think this is enough combat orientated spells?
VM, Bane, HW, Thunderwave, and maybe the odd planted Suggestion if Bane is not working.
