A character's Presence Tier is a numerical indicator of their capacity to passively maintain their will over magical artifacts, spirits, or other beings. As they level up, a character's Presence Tier will continue to increase. Magic items, mounts, and the like will typically have the required Tier it takes to use them specified. A character can only maintain control over things with a total Tier less than or equal to their Presence Tier. Using something that requires Presence takes Attunement. Deattunement is required to free up Presence for another purpose.
Note: This is just a generalization of Item Tiers from Roekron.
The levels at which characters gain Presence are shown highlighted in the table below.
