Power Tiers
To help Game Masters determine which player character levels a magic item is appropriate for, each item is assigned a power tier.
Tier 1: Levels 1 – 4
Common and Uncommon items for characters still learning their abilities.
Tier 2: Levels 5 – 10
Uncommon and Rare items for characters who are seasoned adventurers.
Tier 3: Levels 11 – 16
Very Rare items for characters who are established masters of their class.
Tier 4: Levels 17 +
Legendary items for characters who are like superheroes or demigods.
An item’s power tier is only a suggestion, and the GM should consider how each item would best fit with their campaign and player characters.
