Very strange thing, what did contain Rod of the Callieach? I think it had one of the Eblis Stones, i mean first it has red stone in it and it had alot of power(made Moagim invincible) and than smiths used it to make a Sunhammer(if i record well).
I think the only stones that has these powers are eblis stones(from all artifacts that we saw and heard in myth games).
Ah and i would like to know what does Watcher has in his left hand, seems like magic stick :) Or maybe its like rod and it makes him immortal? or helps him escape? In TFL he has only his sword, and yes mb he don't use his stick because he hadn't the other hand.
