Father Illearth/Lord of Banefire - why?

[Zurai]

My point is though that producing what, 5 items JUST to summon Father Illearth is more than a little extravagant because he does nothing signifigant. He's just a big guy with hard skin. If you have earth magic, you can build lots of big guys with hard skin by going up Construction.

Now, if he did something like summoned corrupted earth elementals, or had some kind of blood vengeance effect on him (hey, he IS tainted with blood magic and craves blood now...) then maybe it'd be worth all that effort. Otherwise I'd rather cast Demon Knights or Infernal Crusades.

Or maybe he could get, say, 1 blood slave/turn... after all, people sacrificed blood to him, that's how he got corrupted. It's not like that would be horribly overpowered, especially since he's unique.
