Wand Gameplay/Spell Runes

I have been toying with being a caster type recently and have come to a split opinion about wands…
ive been juggling the wand with another weapon to compensate for the wand’s lack of a good moveset but i had an idea

I like the idea of a wand being an off-hand weapon akin to the bows, where i could carry a small scepter, or dagger to build focus rather than swapping making combat much less awkward, the wand is powerful sure, but i like that fact that you would need to parry or dodge and not be able to block while you have such a good powerful tool.
