A few weeks ago, in an interview with Yoshi-P, it was said that the Zodiak weapons will have customisable stats (I'm guessing secondary). I can't help but wonder this was possibly mistranslated and instead was talking about the current book system (Where you can choose books to upgrade only current available stats on the relic)

The reason I ask this is because I'm planning to upgrade my SMN relic. However, as most summoners will know, the SMN relic is equiped with spell speed which is a horrible secondary stat for us. I'd feel more comfortable upgrading this relic if I knew I could change this spell speed to something like crit or accuracy later on.

Would a dev be able to confirm this if possible?

Cheers
