Shadow in the Warp All enemy units and models with the Psyker, Psychic Pilot or Brotherhood of Psykers
special rules suffer a -3 penalty to their Leadership whilst they are within 12" of one or
more models with the Shadow in the Warp special rule.
Synapse Creature Models with the Synapse Creature special rule have a synapse range of 12". Friendly
Codex: Tyranids models within this synapse range, including the Synapse Creatures
themselves, have the Fearless special rule. If a unit from Codex: Tyranids is falling back
and at least one of the unit's models is within a friendly Synapse Creature's synapse range
before the unit moves, the unit automatically Regroups.
