I've been trying to get this question answered for a long time, but after doing serious research on the internet the truth seems to be, nobody knows.

I've seen plenty of theories and some even come with some evidence. But most of those results always come inconclusive, and don't prove to be anymore then RNG coincidence.

Does anyone know for sure what exactly Determination does as a stat? What is it's primary function? Is it truly worth point investment for any class regardless of Offensive or Mental properties?

And if it truly does affect strength like the description claims, would it be better to stack the primary stat or the secondary stat? Is Determination truly worthwhile? Does it only affect Auto-Attacks and Heal Dots or does it affect more?

These're the kinds of things I would like to know about the stat Determination.

Thank you!
