So I used tundra whisper on a weighty champion. Weighty gives lumbering once they move 3 steps. Lumbering states that flying units are not affected by lumbering. I think the reason for this is that first once flying, the champion does not consider it to have lumbering because it has not yet procced. However once the lumbering procs after moving 3 times. Thats when it gets tricky.
