Rotting Leviathan

Enemy units in base contact with a model with this rule suffer -1 to their WS. This has no effect on Animated Constructs.

The hide of some creatures forms a kind of natural armour that grants the model an armour save. The resulting armour save will be stated in brackets. Natural Armour can be combined with other armour as normal.

When charging, units entirely made of models with Swiftstride and M 7 or higher roll 3D6, discard the lowest result, and add the result to their M value. When fleeing or pursuing, they roll 3D6, rather than 2D6.

When charging, units entirely made of models with Swiftstride and M 6 or lower roll 2D6, and add the result to their M value. Whenfleeing or pursuing, they roll 3D6, and discard the lowest result.

Swiftstride has no effect on models using a M value lower than 4.

Swiftstride M6 or lower
Charging: M + 2D6
Failed Charge: 2D6
Fleeing/Pursuing: 3D6 (discard the lowest)

Swiftstride M7 or more
Charging: M + 3D6 (discard the lowest)
Failed Charge: 3D6 (discard the lowest)
Fleeing/Pursuing: 3D6

All units with Undead have  Animated Construct, Fear, and Unstable. However, they may make march moves if they are within 12" of the army's General.

If a model with Killing Blow rolls a 6 to wound in close combat, they automatically slay their opponent – regardless of the number of wounds on the victim's profile. Armour saves and regeneration saves cannot be taken against a Killing Blow. Ward saves may be taken as normal.

Killing Blow is only effective against Infantry, Cavalry and War beasts. Against Monstrous Infantry, Monstrous Cavalry and Monsters, a successful Killing Blow only inflicts one Wound which Ignores Armour saves. Against other troop types, it has no effect.

Note that if a Killing Blow attack wounds automatically, then Killing Blow does not come into play. Unless otherwise specified, Killing Blow applies only to close combat attacks.

For the purposes of combat resolution, successful Killing Blows score the same amount of Wounds as the slain model had remaining until the point of the Killing Blow was inflicted.

Unless specified, Killing Blow only applies to the model's normal Close Combat attacks.

Models that cause Terror also cause Fear. In addition,
the following rules apply. Fear-causing models or
models with Immunity (Fear) treat Terror-causing
monsters as causing Fear, rather than Terror – this is an
exception to the rule that makes Fear-causing creatures
immune to Fear. Terror-causing models have the
Immunity (Fear/Terror) special rule.

Run for Your Lives!
If a Terror-causing creature declares a charge, the target unit must immediately take a Panic test. If the test is passed, all is well and the unit can declare charge reactions normally. If the test is failed, the unit must make a Flee! charge reaction. Note that, if the target unit is not allowed to take any charge reaction (if, for example, the Terror-causing unit charged as a result of a pursuit or a random move), then the target does not take this test.

If a unit wishes to declare a charge against an enemy that causes Terror, it must take a Psychology test to overcome its terror first. If the test is failed, it may not declare the charge against the Terror-causing unit, but may choose to declare a charge against another unit following the rules for Redirecting a Charge. If the Psychology test is passed, the unit may declare the charge as normal.

The model can make a Stomp in addition to its other close combat attacks. A Stomp has Always Strikes Last, and inflicts D6 (or D3 against lone Infantry models and skirmishers) automatic hits, at the model's S, on one enemy Infantry, War Beasts or Swarm unit in base contact with the model.

Aquatic models can move within any area of water on the battlefield as if it were open ground. They are still subject to any special effects that specific terrain may have.

The models can march, claim rank bonus and be steadfast even when in water. If every model in a unit is Aquatic, and the majority of the unit is within water terrain, enemies shooting at that unit suffer an additional -1 To Hit penalty.
