Yeah, you don't have to restrict as many as the bard, I'm primarily looking at how you'd restrict the schools to still keep with the primary schools, and I guess the feel, of the artificer. Necromancy and enchantment seem to be no brainless since their current spell list has only a single spell from each, and to me, the schools of illusion and divination (other than a couple of spells) are both limited and overall don't seem to me to fit the feel of the artificer's spells.Rangers are only banned from Evocations in the Primal spell list. Just saying that we don't need to as extensively block off spell schools as we did with the bard. Necromancy is probably a good one, as is Enchantment (spare the dying and catnap are the spells).
The tricky part of the artificer is that, much like the bard, they want to have access to Primal spells as well as the occasional Divine. How do we do that?
