What are white monoblos weaknesses on monster hunter freedom unite

if you wanna know what element a monster is weak, kill one with raw damage (no element weapon), after you finish the mission, go to the weapon/armor dealer and look for the armor it produces, check the elements it has, the one that is negative or has the least amount of resistance is also the monster's weakness.
for the subspecies of monoblos and diablos, ice is their weakness.
If you want to know the spot where you can deal the most damage it is the tail.
