I'm barely interested in Pyros because the multi-layered RNG in Pagos has put me off (I like Anemos tho). But allow me to express a feeling I had while reading this:

"The secondaries [of your relic] are randomized so if you want high stats, you're going to have to reroll multiple times"
Oh come on. I retire from grindy-RNG-fest korean mmo to play this game only to see this kind of thing haunts me back?
