Adamantine Dragon stats -- Please Help

[Kyrinn S. Eis]

Hi,

I've been trying to track down the write-up for the Adamantine Dragon.

Your help is appreciated.
Thanks.

I dont remember seeing an admantine Dragon anywhere except in the Immortals Handbook... as one of its most powerful creatures (CR in the 90's if i remember correctly)

Though its been quite a while since i looked through that book as nothing i've ever ran required CR 80+ creatures.

D&D 4.0, Monster Manual 2. My friend and I are converting it this weekend. Will help when we're done.

According to this index there was 3.5 Adamantine Dragon in Dragon Magazine #321.
