Not sure what Salan changed but i do know a little about it.
STR: no cap
FOC: no cap
DEX: 500 cap
VIT: 1000 cap
Same info with more detail below:
STR: no cap for dmg gain, you get +0.4% crit dmg per point spent untill you cap out at 400% from STR at +1000 str.
FOC: no cap for dmg gain,+60% chance to execute, takes more and more points to get +1 mana.
DEX: Caps out at 500 dex +63.8% dodge/crit chance, +100% fumble recovery. You gain nothing after 500 points.
VIT: caps out at +550% all armor(at 1000 vit) and +51% Block chance (at 500 vit), you stop getting health from VIT at +1,000 if it is still as it was before the revamp of synergies, VIt gets progressively more and more valuable per points spent, you start out getting +10hp per point, and i believe it goes up to +25-30hp per point spent near the cap (700-1,000). at 1000 VIT you have gotten a totall of 19981 Health from Vitality.
