I think enchanted weapons are for non-magic users more than anything so I have an idea: maybe The weapons could use your magika? What does everyone think?
It was done for a mod in Oblivion. I can't remember the mod's name, but you would basically cast a spell that would initiate the 'scribing' of a the next spell you cast unto your mundane weapon of choice. So you could for example bind "Fireball" to your Silver Claymore and your weapon would then blast fireballs when swung, provided you had the magicka to fuel the spell. In the case of this mod it would also increase the corresponding magic skill and had a configuration for deciding the multiplier of magicka cost to cast a spell in such a manner compared to manually casting.
I remember tying the Force Push spell from Midas Magic to my sword and sending enemies flying with every blow. Pretty neat! :hubbahubba:
In my opinion, that approach works best for hybrid Wizard/Warriors or 'Spellswords'; characters with limited melee skills or low magicka tend to get shafted. So as a replacement for the enchantment system it's probably a poor plan, but as an additional system it could be sweet.
How to manage staves? Staves that do ranged magic is in trailer, they would either be a gun with unlimited ammo or so weak they would be worthless. Yes you could have a cooldown but a long cooldown would make them pretty useless again, and a 1 second one would simply reduce damage / second.
In my opinion, the way that staves are implemented should be changed in its entirety. In this current implementation, rather than being the trusty companion of gnarled old mages, they're a warrior's sidearm, providing magical utility where physical prowess fails. Potions already do that and scrolls already do that. Staves shouldn't be about blasting random magical spells but instead as magical foci, improving the magical capabilities of the wielder, either by increasing his skills in appropriate spell school, or somehow decreasing his spell costs, reducing his chance to fail or such. Probably won't happen, but I think it'd be neat if the staff was used to channel your own magical power rather than simply being some added firepower.
