Equip-type Magic

Hello, something in one of the BST threads caught my eye so I felt like bringing up a related issue~

It was just mentioned by Camate that having unique jug pets usable when Guttler is equipped would be possible.

Also, the item "Twilight Cloak" which does something similar - enables you to cast Impact.

If these can exist...why not add unique spells that can only be used when Claustrum, Laevateinn, Mjollnir, Yagrush etc. are equipped? Any other mage-type(BRD too) Relic/Mythic/Emp should also apply. Things like Claustrum are widely regarded as junk items, not worth the time and effort to obtain by the majority of the community. Wouldn't it be nice to GIVE them something worth the effort of obtaining them?

Spells that could possibly be added:
BLM = Ultima(this could be white magic too), Meteor, Death
WHM = Arise(either reduced or no weakness timer)
SMN = Tough one, putting on a new special summon might be considered too difficult...If not, though, there's still options out there, I'm sure...Unicorn, Ixion, Bahamut, Phoenix...Or entirely new recurring summons seen in the Final Fantasy series. Or perhaps put in enhanced forms of the spirits?
SCH = Another tough one~ Kaustra +1?

It'd be nice if there were simply better incentive to pursue mage relics or mythics. The possibility is also open for non-mage jobs. I know PLDs could use the love!

Just throwin' another idea out there.

Someone mentioned something similar in the hvergelmir thread, it'd be pretty sweet if mythics gave everyone a unqiue spell. I might even consider working on one if that were the case heh.

Perhaps they can add this to the level 95+ mythic magian trial...
