Campaigns using the Spelljammer setting add the following terms to those presented in the Monster Manual.
Natural Spelljammer (Su): A natural spelljammer can attain spelljamming speed (100M miles per day) without the use of a spelljamming helm. This ability has the same requirements for being far away from large objects as a ship with a spelljamming helm.
This ability provides no tactical rating (see Tactical Rating, below), unless otherwise stated in the creature's entry.
Only phlogiston or wildspace creatures (see Phlogiston Subtype and Wildspace Subtype) can have this ability.
Phlogiston Subtype: A subtype applied only to outsiders. Creatures with this subtype are native to the phlogiston. These creatures almost always have fly speeds with good or better maneuverability and can move freely in space. Those with average or worse maneuverability usually have the Hover bonus feat. (See the Monster Manual for more information on the Hover feat.)
Phlogiston creatures are rarely found in wildspace or on other planes, and are practically unheard of on planets.
Traits: A phlogiston creature possesses the following traits (unless otherwise noted in the creatures entry).
Tactical Rating (Su): Creatures with a tactical rating (TR) can naturally move on the ship scale when not within the atmosphere of a larger object.
This ability provides no natural spelljamming ability (see Natural Spelljammer), unless otherwise stated in the creature's entry.
Only phlogiston or wildspace creatures (see Phlogiston Subtype and Wildspace Subtype) can have this ability.
Wildspace Subtype: This subtype is often used for creatures that spend most—if not all—of their time in wildspace away from large gravity wells. These creatures almost always have fly speeds with good or better maneuverability and can move freely in space. Those with average or worse maneuverability usually have the Hover bonus feat. (See the Monster Manual for more information on the Hover feat.)
Some wildspace creatures also spend a lot of time in the phlogiston.
Traits: A wildspace creature possesses the following traits (unless otherwise noted in the creatures entry).
