PC on Frost Artifact

Normally I would merch this but it does have 2 inherent mods so could someone please tell me if it is worth selling or just merch food.

Frost Artifact (Gold)
Energy +12 (Requires 10 Water Magic)
Armor +5 (While Enchanted)
Halves Casting Time of Spells (Chance: 9%)

Thanks for your time.

Merch, pretty usless mods. It might be worth if mods are 19-20% HCT
