Is a relic worth it?

[Deceptus]

No.

It has zero way to do it solo, and the time investment is pretty insane for a single weapon and I have all jobs to 80 so I'm not doing it.

Especially when you consider you could invest roughly 12 days in the Ex roulette and have enough tomes to get a better weapon.

or try Emerald EX for more RNG based approach.

or spend 80K-130K on an HQ 510 weapon from the market board.

Sad, but true. I imagine these relics will become harder to obtain than even the eureka weapons. As far as I am aware, Castrum won't even pop unless there are a specific amount of qualifying players in a zone. I cannot believe SE thought any of this was a good idea.

100% accurate. This relic hasn't been futureproofed AT ALL. And that's a bad thing.
