A Giant must test to see whether it falls over if any of the following apply:
When it is beaten in close combat. Test once results are established but before taking a Break test.
If it is fleeing at the start of the Movement phase.
When it crosses an obstacle. Test when the obstacle is reached.
If the Giant decides to Jump Up and Down on an enemy. Test immediately beforehand.
To see if a Giant falls over, roll a D6. If the dice roll is a 1, the Giant falls over. A slain Giant falls over automatically.
To determine in which direction the Giant falls, roll a scatter dice. Place the Fallen Giant template with its feet at the model’s base and its head in the direction of the fall. Any models completely under the template are automatically hit. Any models partly covered are hit on a 4+.
A model hit by a falling Giant takes a Strength 6 hit causing D3 wounds. If the unit is in combat and the Giant has fallen over whilst attempting to Jump Up and Down, Wounds inflicted by a falling Giant count towards the combat result.
A Giant that falls over automatically suffers 1 Wound with no armour saves allowed. If the Giant is in combat, then this Wound counts towards the combat resolution.
Once on the ground (you may lie the model down if you wish) a Giant gets up in his following Movement phase, but may not move that turn.
Whilst on the ground, a Giant may not attack, but he can still defend himself so the enemy must still roll to score hits on him. If forced to flee whilst on the Ground, the Giant is slain. If the Giant gets the opportunity to pursue his foes whilst he’s on the ground, he stands up instead. A Giant may attack in close combat as usual on the turn he stands up.
