My main problem with Thunderwave is that I've tried to focus on bonus action and debuffing spells, using a rapier and Smites for damage. Plus we've got enough casters that we don't really need more damaging spells.
FWIW my Cantrips are Mending so we never need to roll to remake broken gear, and Prestidigitation because it's got some utility and it's an easy way to clean before going into town. My current plan is Paladin 1/Bard 1/Paladin+4/Bard+2/Paladin+1/Bard+lots. I would have only gone to Paladin 5, but that Aura bonus is just too tempting (although not enough to delay Expertise to later than level 8).
Huh, books are 25 gp. So, let me work out my gear with that in mind, looks like I won't need a cart.
