well i got 1 from it so far, according to the wiki the chance is 10%, better than nothing i guess. The problem with the 5 stamina one is, i can not reliable clear it, i am depending on shao assassinate here in addition to my cypria to be a dodge tank for the black armors... also: i can not "do the start that videos do" since my katie is dead before i can even think about using a healer...
