I think I've been following you on and off since 2014? Maybe earlier. I first followed you for the MtG content but you've become such a familiar presence in my online life that I've moved over to your twitter, too, now that I've mostly gone there.

Hey Maro, how's your day going?

No but in all seriousness, if it's a mine-shaft that the magical item is coming from, might I suggest a charm made from canary bones that gives the wearer +10 to poison detection and 10ft darkvision?

A battle dress that has +2 to AC and... pockets.

A dog who's fur changes colours depending upon the alignment and trustworthiness of the person stroking it. Loot the whole party can enjoy.

Another thing you could do is give them a little ooze in a jar. No mechanical benefits whatsoever, but they get to have a baby ooze in a jar.

I have one rogue who I occasionally like to give loot to in the form of "gemstones". I say "gemstones" because their appraise score is low, and I can introduce the loot as "things that look like rubies" etc. They've been mimic eggs on more than one occasion.
