Got both of these on round 1 from a Mr peeks appearance. I got the necrofluid gauntlet, raygun mark 2, tier 3 pack crystal and a legendary aether tool.
I did get about 8 perks as well, I just couldn't take them all because of the relic.
interestingly I died on round 1 the game before after using a gift card gobble gum so this made me feel better about that blunder (unless I've accidentally discovered a hidden feature)
