Helm of Nabu, Crimson Gem of Cytorrak vs....Mjolnir, Power Ring
OK ..............
You the fanboy/fangirl.....get 6 months to train, prep, get acclimated with either group of aforementioned items. HOWEVER your archenemy (a troll from your favorite comic book site 😉 ) gets the same amount of time to prep and train. Once your prep time is completed you HAVE to fight to the death... Which artifacts of power would you use and why???
.......to appease some flamers you can have an adamantium skeleton...not that it would matter at all.
