Endospore

Uses an internal slot; its type defines its basic job in a connection chain.

This is its primary activation method; rarity and the surrounding build can still alter its rhythm.

Needs a mitochondrion or another Overload source; insufficient supply limits repeated use.

It has no mandatory target type, so placement can follow its effect and slot requirements.

No additional modifier-compatibility tag is listed; rely on the effect description.

Rarity normally governs numeric scaling; affixes and Excitable status can further change connection or Overload behavior.

Relative likelihood in random offer pools; this is not a damage or power rating.
