The Soullocked Sinstone pet is already in the database and is currently having it's attempt tracked on Secret Treasures in Revendreth. Allthough this is somewhat true, the community seems to have narrowed this down to only drop from one of the Secret Treasures, not all/any of them. That means we instead of just tracking the treasure chest name have to track the specific ID (if possible).

Are there any other items (that we're tracking) with the same restriction? IIRC we can only scan the GameTooltip for an object's name; everything else might require a workaround, like checking the map coordinates. At least I don't think we can get the object ID somehow, unless Blizzard has added an API to do so in the past few years.

Also, if the treasure chest is only available once every X months, that makes it even more likely people will waste their time on this.

Maybe just adding a sourceText to indicate the limitation would be a good start, so people can do some research first?

Looking at wowhead comments, it seems this may be a bug (should drop from all chests, but only drops from one)?

Also in the comments: People opening hundreds of "other" chests due to Rarity adding attempts. Can we fix this? Late, but still...
