Nightwing has incapacitate and two lightning bolts. Does this mean he can add two action tokens to one target at range?

Rupert has incapacitate and THREE lightning bolts. Does this mean he can add two action tokens to target A and one to target B at range?

No. It's not 2-3 attacks, it's 2-3 targets. Nightwing can add 1 token each to 2 targets, and Rupert can add 1 token each to 3 targets (lotsa fun :-))

Another neat incapacitate trick is to park someone with enhancement next to the attacker. This way you will not only give each target an action token, but you will inflict one click of damage to each target hit (on top of pushing damage, if applicable)

This is legal because Inc reduces the damage delt to 0. Enhancement increases this value by one.

My favorite combo is the E Archangel (or LE warren worthington) and a V Psylocke. Running shot, double Inc AND 1 damage to each target!

Nasty!

Just to note for the Incap+Enhance: The Enhanced damage CAN be reduced by Toughness or its ilk. The PUSH damage can NOT though. Push can never be reduced. Enhancement is a normal damage point that can be.

With Willpower, yes it can

It is like a critical hit. It does one extra damage, not one automatic damage!
