Just in case someone else is wondering if the Stat describe in the link above is still being used today, Yes it still is, But I can only assure it on weapons, I didn't bother with other mechanics it affects.
I feel like not playing rose for a while because I don't know how to properly distribute my stat points
and I'm afraid that the mechanics describe in the link above is not being used anymore.
Since I don't wanna quit Rose but feel like not playing just because of the Stat I had to Test it myself.
Took time and I had to reset my lvl54 Char, but I won't be using it anymore so no harm done.
I tested all weapons and It seems that the above link is still being used today,
There was only one thing that was wrong
The Dual Swords
Link on the above says
I tested it and it was the opposite,
