What's up with Archdemons???

[Metathron]

Well, they are very agile, what with teleportation...

And they can't be cursed for more than a turn...

But yeah, I don't think much of them either.

Then again, I found most of the level 5 units to be underwhelming. I find some of the lower level units to be much more cost effective (and just plain effective) than level 5s.
