Giant Chaos Spawn

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.

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

Models with Random Attacks do not have a normal number for their A characteristic, but rather a dice roll. Each time a model with this rule comes to strike blows, roll the indicated dice, adding any modifiers shown, to determine the number of attacks that the model will make, then roll to hit as normal. If a unit contains more than one model with this rule, always roll separately for each model.

Models with Random Movement do not have a M value, but rather a dice roll. This is the distance they move, charge, pursue, overrun and flee – they cannot march. If a model has Random Movement and Swiftstride, then Swiftstride is not used. Note that certain Random Movement rolls can result in the model having a M value higher than 10 – this is an exception to the usual maximum.

Models with Random Movement cannot declare charges, and are always moved in the Compulsory Moves sub-phase. When the model moves, first pivot it about its centre to face the direction in which you wish it to travel. Then move the model after rolling the specific dice. No other pivots can be made.

There's a chance that the model's peculiar movement will cause it to come into contact with an enemy, so measure the distance in a straight line before the model is moved. If the move is found to take the unit’s front arc into contact with an enemy, then it counts as charging, and this is resolved using the normal rules for charges and using the distance rolled as its charge range. Charge reactions cannot be declared against enemies with Random Movement.

If the random move brings the unit to within 1" of a friendly unit or impassable terrain, it stops immediately and cannot move further during that Movement phase.

If two or more models in a unit have the Random Movement, pivot the unit about its centre, then roll the dice only once to determine how for the unit moves. If models in the unit have a different Random Movement value, use the slowest for the entire unit.

A Random Move counts as a "normal" move for triggering a Dangerous Terrain test, unless the model is making a charge, pursuit or flee move, in which case it counts as a move of the appropriate type.

Unbrekable Models have Immunity (Psychology) and passes Break tests automatically. Characters that are Unbreakable may only join units that are also Unbreakable, and characters that are not Unbreakable are not permitted to join units that are Unbreakable (even if a character was to become temporarily Unbreakable for some reason).
