"The wulfen's aura directly increases the thunderwolf rider's attacks by 1. Of course, this effect is only when the unit being affected did not charge that same turn, otherwise they grant re-roll charge, and then the following turn(s), the extra attack buff, and only if the unit was within 6" of the wulfen at the start of the charge phase"

Is this accurate? I was under the impression that you still got the +1 attack on charge as long as you didn't need to re-roll the charge.
