getting back into the game and wondering if these are worth anything!

I'd merch the Plagueborn Sword; maybe take the time to sell the mods for 1e/ea or so.

Although it's perfect, it's a common chest run skin and high req; I'd say only dual vamp/zealous and maybe +5e have value past q9 for os melee.

I'd put the shield up for sale to see what the offers are. Not really sure on a set price for 1-off perfect dual, but there will be some interest in the +hp (enchant) +10ar combo.
