So shadowblade is a really cool skill, but in 5e players are allowed to throw the blade and re-summon it as a bonus action.
I would like to request the skill be added to the base spell set as a whole with the above implemented for dagger tossing.
I would also request that the existing skill version from Shadow Blade Ring, not require concentration but only that the ring be equipped for it to be present, a more permanent special unique version.
This would also enable the potential for players to even dual wield Shadow Blades.
