[Throws possible against targets already touching bases?]

Is is possible to throw a model into another model if those two are already touching bases? Resulting in a no movement / immediate collision?

[Range check on additional checks such as Doomsday Chair]

So you still go through all the normal attack steps, but with the additional rule that they would need to be in R2 of the original target?

[Range check on additional checks such as Doomsday Chair]

When making additional attacks such as from MODOK's Doomsday Chair Whirling Blades, does the target character only need to be within R2 of the original target, or R2 of original target and R3 of MODOK per Doomsday Chair Range? Unsure how examples like these translate into the attack step order chart. My guess would be that since the ability (Whirling Blades) mentions the target, range, and power cost reduction, you essentially skip to step 4.
