Buff stacking

Hi everybody,

i'm new in this forum and not a native speaker. Sorry in advance for my bad grammar. Hopefully im understandable.

I'm wondering whether buffs are stacking or not.

I want to know if the leader ability of CD (getting special dmg + when dodging) stacks with other special dmg+ (like QGJ or Poggle).

So, does it stack?

Thanks in advance.

Regards
