Ultima Weapon!

Simple Idea, but think its a pretty good one.

By collecting all three primal weapons of your specific job, you can fuse them together at the relic blacksmith to create a Ultima weapon.

Pros: +Goes in line with Ultima's lore, absorbing primal powers to create a strong weapon.

+Would inspire people who have previously cleared those primal fights to again run it for the three weapons needed.

The weapon doesn't need to be on Relic +1 Level, but a Item level 80 weapon from it sounds pretty fair.

+Allows your primal weapons to retain use even after obtaining a standard relic.

Thoughts?

Very good idea. But I think this would be good for a much later point when lvl cap is at 99 and we have much more primals out there.
To be the ultimative Weapon. Nothing should be better than ultima weapon.

I want it to be like the demon's arms weapons from the Tales of games. They get stronger from killing monsters (to a certain limit would be better for this game)
Just make it so only dungeon's and bosses count to get people away from grinding fates to grinding something else :P
