When adding points to stats, the only change is to END and SPR. Stats change in accordance to stats on gears. STR only accepts 10% of stat number on gear. Example: my pet has +10 on all stats, so all stats on bottom portion of stat window change by 10, except DMG (which only increases by 1), and free stat has no effect regardless of what it says.
I unequipped all gear and my STR is 633 +50, when i look at DMG value, it's only 63 (10% of 633) and the +50 points mean nothing. Is this normal?
So, I actually see 2 problems. adding points to stats only work on END and SPR, and STR only accepts 10% of actual value of Base STR and STR added by gears.
