The Massive Iron Crown of Morgoth [0,+0]

Two Silmarils of Feanor blaze from the thunderous crown of twisted iron.
The corrupted metal feels at once as infernal as hellfire and as chilling
as the Outer Darkness. One protrusion from the crown is abruptly ended
where a third jewel might have shone.
It provides light (radius 1) forever. It increases your strength,
intelligence, wisdom, dexterity, constitution, charisma and
infravision by 125. It provides resistance to acid, electricity, fire
, cold, poison, light, dark, confusion, nether and nexus. It allows
you to see invisible monsters. It gives telepathic powers. It is
permanently cursed. It cannot be harmed by acid, cold, lightning or
fire.
