-Enhances Flourish point gain. Instead of one, you'd get 2, and instead of two, you'd get 3.

-Enhances Jump makes all jumps Crits... or so it seems.

-Attacking faster and reducing the rate of overloads!

-Enhances Divine Viel makes Divine Viel (AoE -na) effect work all the time.

-Enhances Convert's working method is unknown. From the story though, using it for MP leaves you with 1/2 your HP and full MP.
From what the people on Allak said, doing the standard RDM convert (Low MP and high HP) left them with Mid HP and full MP. Going on that, I think it takes half of your MP and HP, doubles it, and adds it to the other pool. I.E. 500 HP and 200 MP would become 450 HP and 600 MP.
So, 500 HP would be cut in half. Leaving you with 250 HP and 250 from convert. Which would be doubled and added to MP.
200 MP gets cut into 100. 100 of which is doubled into 200 which is added to HP.
So 200 + 250 = 450 HP and 100 + 500 MP = 600 MP.

-No info on how Sneak Attack or Trick Attack is affected.

-They didn't have cards, so couldn't play with "Enhances 'Quick Draw' effect". Though, I think its +damage and +hit%.
Also, the new weaponskills can be obtained VIA quests. Should be interesting...
