I happen to have two equal “High Speaker’s Accretion” trinkets. Both are 1/8 Adventurer, ilvl 571. (When the second one dropped I tried to give it away but nobody wanted it.) Mr. Robot tells me it’s the best trinket I have, but constantly wants me to equip the other one.
This is on me for having two and not having vendored it yet, which I will do, but I thought I’d let you know since it’s completely the same - one doesn’t have a tertiary stat or anything.
We usually try to avoid spurious changes like that – if you could post a snapshot ID I’ll try out your specific case and see what’s up. Instructions on how to do that are in this post (or the little excerpt below has all the info you need to make one):
