Minor Boon

Minor Boon is a boon form in The Nether that can stack up to 10 at a time. Players gain boons from chests, pots, secrets and high-value targets.

Collecting enough duplicates of a Minor Boon earns a scroll from the Mysterium, which permanently raises how many stacks of that boon you can carry. Other guides call these rewards Faded Scrolls and say that once a scroll is owned, each pickup of that boon grants more than one stack.
