Prism Staff (name pending)

[Kristal]

Nobody wants a staff with tons of 100 subpar stats, and if they do they should keep quiet. Unless this prism staff can offer the same benefits as the magian 99 staves then this prism staff is a waste of time and is ~2 years too late. Any mage that is worth anything uses magian staves to augment their primary magical functions and a prism staff will do nothing to reduce the need for tons of magian staves...

You seem to miss the purpose of the Prism Staff. It's not intended to replace the ultimate magian staves.
Prism Staff WOULD beat magian staves on their secondary bonus, and that is exactly where the attractiveness lies.
As RDM, I never bothered with the magian staves except Arka IV, because our nuking is subpar no matter what you throw at it, and magic accuracy is no problem when stuff is either outright immune or unable to resist RDM's enfeebling skill to any degree.

Simply put, Prism Staff is the RDM of staves. You'd use a BLM for nuking or a WHM for healing (magian staves), but if you can cope with less then maxed nuking/healing, RDM can do both and free up a slot.

I just hope obtaining it involves the lvl 51 NQ/HQ elemental staves, so that the last remaining vestige of that market isn't utterly destroyed. (And I can put my collection of hand-crafted HQ staves to good use.)
