It's a great piece for a balanced nuking set. Lemegeton Medallion (even +1) will produce more Magic Accuracy and Ugg. Pendant will produce higher DMG in higher tier nukes, but, for a well rounded piece it really shines in giving you a bit of everything, including your own personal potency based enfeebling neck piece for Slow/Para. Completely acceptable to main this for all but healing purposes and hMP purposes. 100% dorp from Ironclad Pulverizer (the most sought after boss for Atma) so shouldn't be any difficulty in obtaining it. Good luck!
