I would have been inclined to disagree with you. It seems I tried this many Seasons ago, with an alternate Character of a different Mainstat from my main Character, and received items appropriate for my main Character. So, I decided to test this… just now.
I loaded up my Solo Season 34 Demon Hunter. I picked an Act where I had the least amount of Bounty Mats. (Act 5). With the Altar fully unlocked I received two Bounty Caches. I put them in my Stash.
I then switched to my alternate Crusader and let him open the two Bounty Caches. He received:
# | Item | Type | Attribute | Class Specific | ||||
---|---|---|---|---|---|---|---|---|
2x | Helltrapper | Hand Crossbow | Dexterity | Hatred Regeneration | ||||
1x | Salvation | Crusader Shield | Strength | Wrath Regeneration | ||||
1x | Death’s Bargain | Pants | Strength | None | ||||
1x | 2-Hand Rare | Axe | Strength | None | ||||
1x | Rare | Belt | Strength | %Punish Damage |
The Helltrappers are Bounty-specific Legendary Hand Crossbows, so it’s no surprise they rolled with Dexterity and Hatred Regeneration. Death’s Bargain is also a Bounty-specific item. However, I was surprised that this and the rest of the items rolled with Strength. And some with Crusader-only Properties. The Bounty-specific Salvation rolling with Strength and Wrath Regeneration wasn’t a surprise because of it being a Crusader Shield.
But, it seems you are correct.
The Class that opens the Bounty Cache(s) determines the Mainstat and Properties
I am now inclined to use a Mark Twain quote that @yessquire recently posted in these forums:
“The older I get, the more clearly I remember things that never happened.”
