I just encountered the weirdest thing in the arena...

I'll raise you:

P.S. This is still the worst:

I don’t know how well this qualifies, but I remember seeing this on my Arena Defence list some time ago.

When skill inheritance was released I put obstruct on him thinking it was great idea, probably that guy just don't have an idea what he is doing, like I was lol.

Obstruct does one useful thing, and that is the fact that it actually blocks Wings of Mercy.

Yea, that's about it.
