Been suggested a few times.
I don't think staffs have been confirmed, but I do hope this time they act as spell amplifiers. Would be good for pure-mage type characters.
Yes, spell amplifiers, and perhaps items that reduce the amount of magicka taken from the spellcaster.
That would be a great idea, rather than just using them like has been done in the past (oh! I need a lightning spell, time to switch staffs. Oh! I need a fire spell, gotta switch staffs again, etc).
I HATE how in oblivion anyone can use any staff... they should find some way to make them usefull FOR MAGES, I mean... I want my mage to be using staffs, not my warrior! (because staffs are actually more usefull for non-mage characters, since they don't have the skills to cast spells by their own)
That's why I think making a staff a magic amplifier is such a good idea. Sure, there can be some that only amply certain spells, or even grant certain spells, but to be true to fantasy lore in general, changing fundamentally how wizard staffs are used in TES is a must. They really ought to focus on magic amplification rather than just spell casting.
