I like this idea a lot. There could be multiple aspects of a staff that you could tailor to achieve a certain effect. The stone at the top could be enchanted or replaced with some sort of relic that would be given as a quest reward. The material that fuses the stone to the staff could be customized. The staff itself could have different effects. and finally you could have little inscriptions written on scrolls and trophies such as little strips of rare furs attached to the staff.
Sounds like a really good idea - could also be applied to other weapons, too.
How about each wizard staff has three gem slots: A passive stone, which could be enchanted with any constant effect, including the spell-school enhancing ones you mentioned. Then an active one, which would launch its spell at the target when you press the attack button, and defensive gem which would cast its spell on the caster (or in an area around them) as long as the block button is held down. The quality of the gem would affect the potency of the spell it casts, and the staff itself would provide a separate mana pool that they're cast from, and casting from a staff would still train its magic school.
It sounds pretty good, except the active attack spell stone, because I was thinking more that staves should amplify spells cast, instead of casting their own. The defensive stone sounds good though - maybe holding the cast spell + block casts the defensive spell channels it, draining magicka until the casting is stopped and, while it is being channeled, no other actions can be performed. It could work really well, especially with a companion system: A mage, instead of going offensive, could simply use their magic to shield their companions from enemy attacks whil they fight.
I agree. Your staff melee could just count as a "blunt weapon" attack. However, I think staves shouldn't have their own reservoir of magic. I think instead they should amplify the magic your character already knows. Maybe you can throw a fireball without a staff, but it's wild and unfocused. The staff should amplify and concentrate the character's magic, not replace it. A non-wizard shouldn't be able to do the same thing with a staff as a wizard.
Just what I was thinking.
But, the magic channeled through the staff would depend on the stone - if the staff has an alteration stone (Amethyst as Horseman suggested, and amethyst does actually seem to fit with alteration) then, when you cast an alteration spell with that staff equipped, instead of casting it from your hands, it goes through the staff and comes from the end. For cast on self spells, the animation would be the player opens his arms high to the sides and the staff does the normal thing - I think it would look pretty good, and definitely a reason to watch in 3rd person.
I like the idea of a staff amplifying your magic. This seems the way that the use of staves by the wizards in Tolkien's world worked where a staff did not per se give or grant power to the wielder, but was more an extension of the wielder. That being said, we already have artifacts that come with their own magical powers (such as the Staff of Magnus).
I think that the way staves work should be twofold: A staff should grant power that may lie within the staff to the wielder, but the wielder's access to the staff's inherent power should depend, in a large part, on the capabilities of the wielder. So if I'm a beginner mage and I pick up the Staff of Magnus, there is no doubt that I should be able to use it's power; however, the extent to which I can access and control said power should be limited based on my knowledge of magic. My beginner mage has more power as a result of using the Staff of Magnus, but cannot wield it to the same extent that an Archmage could, for example.
Sounds good, LotR was where I got the idea - it just seems that staves are actually meant to increase the power of the wielder, no have their own special spell - But there could be a completely different type of staff that has it's own spell. These would be unique and rare, and the idea of the player's power determining how well they wield it sounds good.
Melee StavesI understand people thinking that a wizard wouldn't rely on blocking and attacking. However, if you're using a staff to channel your fireballs and then an NPC, with a sword, appears in front of you, you would have no choice but to switch to a melee weapon. Instead, you could block the attack with your staff - it would take significant damage (5-10%?) but would work as a last resort and make it more usable as a weapon.
