So many vague traits

[jigokuro]

I want to make optimal gear in this game about making your own gear, but it's impossible to know what optimal is!
So many traits (and effects) just say 'increases' without any indication how much. Some outright lie, like 'Stats Power' saying "Greatly increases all stats" when it actually only gives +5 all. Compare to Stats++ that is +50 all at 99; 5 is useless! So now I'm wondering if any buff that isn't explicit is actually worth it.
I wanted to do a combination of Miasma Clothes, Status Effect Boost, and Reviver to get a ton of extra stats from self inflicting a status effect, but besides the 20% more damage, the rest could be basically nothing (after all, they don't say 'Greatly' and 'Greatly' was all of 5.) So I'm probably best off just using every atk/def/spd++ and stats++ on everything. Which is honestly sad; why are those traits SO much better than anything else verifiable?
Is there any datamine dump of what effects and traits really give? There isn't a guide on Steam, at least.

As a rule of thumb, traits that don't have levels usually are weaker than fully levelled traits unless their "star" rating is much higher or those with very special effects.

Sadly this game doesn't seem to have been all that well received as evidenced to the lack of informations even on sites that usually give those details for other games of the series.
It's probably also because the difficulty is incredibly low throughout the story, meaning that min-maxing to that point is not required at all.

Honestly yeah, it's hard to justify really taking a big look at any useful traits if pumping your gear full of maxed stat up traits easily does the job as well.
Though it's probably partially because the game makes it really easy to get them.
