is there an update on which mob drops these items?
Jade: You can use up to 5 level gear items above from your level if you use jade of relief. For example: You can use weapon and armor level 65 when your level is 60. Jade duration about 6 days (correction me if I am getting wrong). You are only need 1 Hora Jade box to use 5 level item.
Note: Percentage Hora Jade chance drop is rare. So keep kill it until you get it.
Pine Booster Ability: You can use it to make Aiming Cape/Booster until Grade 99.
Vampire Booster Ability: You can use it to make Blood Cape/Booster until Grade 99.
