I wasn't able to get this enchant when trying ominous and regular vaults.

I looked at the loot table for them in the code and notice it doesn't drop it at all. Thought this was fixed.

Wiki said it was a treasure enchant in vaults but not sure if thats accurate now.

Recipe for Satchel on the wiki doesn't worth either.

Found the recipe for satchel in game. Didn't notice it in the achievements section.

Critical strike still seems unobtainable tho

Critical Strike will be available in the next update alongside void shot in vaults.
