So, just a short simple question, that I haven't found an answer to anywhere else...

I'm a SMN, and as I understand it, Omnitome (EX primal weapon) is an equally or even better weapon than Relic + 1. So now I would like to get it

The question is: Do I have to spend 900 myth tomes on Relic + 1, just to be able to beat the EX primals and get Omnitome ?

If that's the case, that's just wrong.... I thought I would be able to take a different route and skip relic + 1 for now, so that I could spend more tomes on armor.

Appreciate if you explain why or why not Relic + 1 is needed
