Okay so I tested this out with my bst, selbina milk is supposed to recover 40 hp over time. With the Dream Robe +1 on I recovered 58 HP (without healing or any other sort of regen). So the "enahancement" is 18 HP.
ok just got this piece after about an hour and a half of running in windy, sandy and bastok. all you need to do is /cheer at the Trent which spawn twice a day, more info about this can be found at "Dream Robe" forum. when you got your Dream robe (that would be after 4 runs) you just do it one more time in any city, I did it in my hometown. When you're done the smilebringer will give you the Dream Robe +1
Happy hunting and a merry christmas to all of you!
