Wound calculator for Warhammer Fantasy:
Note: Not every special rule is listed here.
You will need to select the appropriate options yourself.
e.g. for Always Strikes First you will need to check the initiative and then select "Reroll missed to hit rolls".
For Fire attacks you need to deactivate the regeneration of the enemy.
Note 2: Use your attacks plus all the support attacks as attack number. e.g. 4 for a horde with spears.
