Relics of the Realms

The items in this chapter are not found in dungeons. They are the residue of cosmological events - fragments of divine domains, crystallizations of specific resonant frequencies, objects that have absorbed so much of a particular reality's character that they carry that character wherever they go.

A shard of divine influence is not a bonus. It is a fragment of a living god's will, hardened into something a mortal can hold.

On Stacking and Cosmological Items

Standard magic stacking rules apply to all numeric bonuses. The qualitative effects - perception, planar interaction, cosmological sensing - do not stack mechanically but combine narratively. A party that has assembled a coherent cosmological toolkit - things that work together - has done something interesting. Reward it by making the cosmological layer genuinely explorable to them.

When a relic would bypass a major story obstacle, sealed realm, divine ward, Gate Keeper judgment, or campaign-defining mystery, the DN decides how the relic interacts with that force.
