Slug Egg

Slug Egg is the electrifying egg of a Plug Slug. It is a simple creature-related item whose entire described identity is tied to that species: a charged, living egg associated with the Plug Slug.

The available text gives no additional mechanics, use cases, or special interactions beyond that basic definition. As such, Slug Egg is best understood as the egg form connected to Plug Slugs, and any practical relevance it has in play would come from its relationship to that creature rather than from any separate behavior of its own.
