Blast weapons unleash explosive attacks that can damage multiple models.
When a blast weapon hits its target, resolve the attack against the target as normal. Additionally, when a blast weapon hits its target, the two models closest to the target that are also within 2” of it suffer blast damage rolls equal to the POW of the weapon. If multiple models are equal distant from the target, randomize between them to determine which two models suffer the blast damage.
When a blast weapon misses its target, the target still suffers a blast damage roll equal to the POW of the weapon.
Blast damage is explosive damage. Blast damage is also considered to be damage caused by the type of attack and damage type of the attack causing blast damage. For example, if a ranged weapon with kinetic damage type does blast damage, that damage is considered to be caused by a ranged attack and is both kinetic and explosive damage.
Intercept Driver: When a friendly model is targeted and hit by an enemy attack while within 5" of this model, this model can spike once to be hit instead of the model originally targeted.
If a model is targeted and hit by a blast weapon, and then another model uses intercept driver to be hit instead, what happens? Notably the intercept driver does not become the target of the attack, and is only hit by the attack, but blast damage triggers off of the target being hit. Also of note is warcaster does not have the language that warmachine does where models that take blast damage are also “hit” by the attack.
a) The intercept driver model is hit and blast damage is taken from their base, not the original target’s, so the 2 closest models within 2" of the model using intercept driver receive blast damage rolls.
b) The targeted model was still hit by the attack before intercept driver was used but did not suffer the damage roll, thus it stays as the “center” of the blast and if the intercept driver model was within 2" it could be eligible to take a blast damage roll.
c) The targeted model is no longer hit because the intercept driver model is “hit instead”, therefore the target cannot be hit by the attack, and no blast damage rolls result from the attack at all.
At the time we played it as b, but on reflection I’m not sure that’s the correct interpretation.
