If I am not mistaken, MapleRoyals implemented a change that a buff will choose to use a stronger buff when both are applied, that is, a weaker buff won't over take a stronger buff when it is applied after a stronger buff. However, when I use my bucc transformation (or super transformation), and pick up a monster card (by pet, unless I have the avoid pet loot nx eq), the monster card effect will overtake my speed or jump. The main annoying thing is transformation has a cool down of roughly 1 minutes, and if I pick up a monster card accidentally right after I cast transformation, I will move like a turtle. I am not too sure if it is a bug or this is how it is suppose to be.
