Champion Galkut's skill 1 says that it attacks 1 enemy and has a chance to break the defense of all enemies. But that is not what happens, this ability only breaks the defense of the attacked enemy. Please fix this so that this champion is worthy of being an epic champion.

Hi!

Galkut's A1 is working as inteded:

There you can clearly see that it is a single target attack, with a single target debuff.
