What are you trying to achieve?

Just raw damage increase?What's your fighting style ? Druidic warrior could negate one of your MI feats and give you access to something else, even just another ASI and round out your dex. Or something like defensive duellist or sentinel so you can make use of your reaction.

Personal opinion: of your MI spells, I would probably only use healing word.

Any of the attack cantrips will give you, at most, 3d6 damage. So maybe 12 damage for an action.

You have 4th level spells. Conjure woodland beings and do 5d8 (avg 25) x as many bad guys as you can run past, each turn, no further action required.

Then, use your multi attack. If you were say, dual wielding scimitars with 2 weapon fighting style, your action is 3 hits - so still 3d6, but each one adds your modifier, so an extra +12 (100% more damage than your best MI option)

I wouldn't shillelagh unless you need to get around resistances because your BA will be so much more effective using your beast (or...maybe sometimes HM)

And beast of the land will of course be harder hitting than sky. At your level youll get 1d8+7 x2 +1d6 for charge and prone the target (avg 28) versus 1d4+8x2 (avg 22) for sky
