Hello, after your reply clarifying the use of wands/staves, I thought over an idea of mine regarding enchanting weapons with elemental damage as a spell in the magic tree.
But my extra edit to this idea is that your use of wands/staves adds a small bonus to the enchantment, nothing great, but it would keep the use of those weapons relevant and adding a stratagem of swapping them out before or during battle to give yourself a slight elemental edge to your ranged or melee attacks.
