How to get Fragmented Souls
Here's a good guide on how to get fragmented souls to buy Festival of the Lost masks. The easiest way is to get bounties from Amanda Holliday, usually you get just one it seems but other bounties can have higher fragmented souls rewards like +10. Daily bounties give you +1, Weekly bounties give you +40 fragmented souls. That's enough to buy a Festival of the Lost mask!
