The trinkets seem on the overpowered size, especially with how potentially early game they can be found, so I have a few suggestions.

-I dont think the fang should have blight chance, just add a crit or damage bonus (maybe remove the armor piercing if the latter) so its more in line with the move the fang is used in.
-The Prismastic Heart seems a bit high, I would lower the blight resist to around 25% or so, and maybe even sack the bleed resist as the Thing doesnt have bleed attacks, so maybe replace it with a debuff or stun resistance.
-The mesmerizing eye is a straight up better version of the Ancestor's Lantern which just feels wrong, maybe sack the surprise stuff and replace it with an accuracy bonus, or only have the reduced surprised by enemy chance.
