To go further, with the new rules, you can choose which stat to use, regardless of which list you choose from. So, as an EK taking Shillelagh, you can choose CHARISMA to cast it.
So, if you rule that a spell that is no longer Wisdom-based is no longer a druid spell, does it means that if it's not INT-based, it's not an EK spell either?
Good question. And it seems to me they've not really thought this through.
I like the decision that you can choose the casting stat. That seems to me to be designed to simplify things for players who get spells from feats and races, so they can use the same stat as their other spells. If that is the underlying philosophy, then it may be they'll rule that when the player decides the casting stat, they can choose to make it a wizard spell even if it now uses charisma. I don't really see a problem here.
In my opinion, if it gives players more options and doesn't introduce game-breaking combinations, that'd be fine.
My one real concern so far is I think they've made a couple of the cantrips too powerful. And that these might affect
game balance somewhat.
- Shillelagh allowing you to choose your casting stat for melee combat is great. But also
increasing a one-handed weapon to a two-handed damage die seems to me overpowered. I kind of think that's the sort of power that should have belonged in a 1st level spell.
- Blade ward can't affect multiple enemies which are attacking other people, as Bane can. But it's better in that it increases your melee AC by an average of 2.5 without using a spell slot, and without any saving throws for any attackers. Again, that seems the kind of power that belongs in a level 1 spell.
- True Strike is also powerful, but as the existing Booming Blade cantrip was similarly powerful, I'm less concerned about it.
