Leviathan

• Each time an attack is made against a SYNAPSE MONSTER unit with this adaptation, an unmodified wound roll of 1-3 always fails, irrespective of any abilities that the weapon or the attacker may have. • Each time an attack is made against a unit with this adaptation (excluding SYNAPSE units), if that unit is within Synaptic Link range of any friendly LEVIATHAN SYNAPSE units, an unmodified wound roll of 1-2 always fails, irrespective of any abilities that the weapon or the attacker may have.

You can swap this hive fleet's Adaptive rule for one of the Feed Biomorphologies or Hunt Biomorphologies on page 61.
