Here’s a clearer and more concise revision with improved readability:
Reach is typically determined by the Caster's Size or the weapon’s reach when using a weapon or an Attack Ability.
In the XZ System, a Caster can interact with objects within their maximum reach—based on their size category rather than weapon reach, such as picking up an inventory object in the encounter, or using an ability within reach.
Feats, spells, and abilities can modify Reach, either increasing or reducing it.
