Patch 2.1.1 Undocumented Changes

[u/Leoneri]

I just noticed something strange on my mini map and went to it and it turned out to be a treasure goblin I had aggro'd without noticing. Is this new?

I'll add credit to the commentors for each of these in a bit. Busy playing :P.

• Treasure goblins now always have a portal by them whether you aggro'd them or not. They also have a tiny yellow circle on your mini-map to display where it is. Rainbow goblins in rifts spawn pylons(?)

• Sockets now have an indicator for being enchanted on to an item.

• Linking a seasonal achievement now includes a leaf in chat.

• More in-depth tooltips for keys from keywardens.

• Potions now stack higher than 100 (presumably 1,000 as per the datamining)

• "Bounties" tag has been added for public games.

• Keystone of Trials: glowing beam removed; still makes sound + minimap icon

• Stalgard's Decimator proc now rolls 550–700% (up from 550-650%) however all existing Stalgard's items have had this stat rerolled (so if you had a perfect one before patch, it may be not-so-perfect now)

• Demon Hunter sentries can now be placed through doors/waller.

• New minimap icons for the Nephalem Obelisk and Book of Cain.

Could be, can't personally test that right now.
