Editing Codex - Tyranids: /tg/'s 8th Edition (section)

===Universal===
*'''Instinctive Behaviour:''' ''Unless controlled or coordinated by the domineering will of the Hive Mind, many Tyranid organisms will revert to their baser instincts.''
::Unless a {{W40kKeyword|<HIVE FLEET>}} unit with this ability is within synapse range of any friendly {{W40kKeyword|<HIVE FLEET>}} {{W40kKeyword|Synapse}} unit, you must subtract 1 from any hit rolls made for it when shooting any target other than the nearest visible enemy unit, and you must subtract 2 from its charge roll if it declares a charge against any unit other than the nearest enemy unit.

*'''Shadow in the Warp:''' ''The unfathomable presence of the Hive Mind radiates out from its synapse creatures, smothering the ability of the psykers who stand before them to draw upon their mystic powers.''
::Enemy {{W40kKeyword|Psykers}} must subtract 1 from any Psychic tests they make and from their Leadership characteristic if they are within 18" of any units with this ability. {{W40kKeyword|Tyranid}} {{W40kKeyword|Psykers}} are not affected.

*'''Synapse:''' ''Some Tyranids serve as synaptic conduits or nodal relays through which a portion of the Hive Mind’s iron will flows, overriding the natural instincts of the swarm.''
::{{W40kKeyword|<HIVE FLEET>}} units automatically pass Morale tests if they are within 12" of any friendly {{W40kKeyword|<HIVE FLEET>}} units with this ability. Also, {{W40kKeyword|<HIVE FLEET>}} units don't suffer from ''Instinctive Behaviour'' if they are within 24" of any friendly {{W40kKeyword|<HIVE FLEET>}} units with this ability.
