Ice dragon and legend type dragon is have same difficult, so 5 dragon on same slot XP

if is 1:1:1, difficult 3 will get only 33.3 %, and after that devide by 5, it will 6.666 %

minimum chance is 0 % (if you verryyyyyy bad luckkky XD), max is 33.3 %. average chance is 6.666 %

boost is just increase level by 6, is not increase any chance.

if you fail 3-4 times, just used another rare dragon.
