Give the possible Eureka 5.X its own weapon, and separate Relic from it

[BillyKaplan]

The didn't add the relic to Diadem they added it to Eureka.

No, Diadem had those pink weapons. And when that wasn't enough they learned and put the relic in Eureka.
And if they designed this around the relic, I ask again - why can I go through the entire place without upgrading my weapon the once? Why can I clear, at the very least, Pagos to Hydatos without even touching my weapon?
Maybe because Eureka wasn't made for the relic hm.

running boring old content ad nauseum

People who spammed A1S until they threw up mini puddles is their own choice and fault. I got a lot of light just farming roulettes, including Mentor, and switching to the weapon whenever applicable. The older light farms you could basically do by playing the game. Eureka is mutually exclusive from anything else by virtue of being instanced.
