I'm a little confused. i was reading in the WOTR book that you need to roll to see the charging distance, and you need a roll to seeif the charge is successful. are the rolls combined for both the things, or are they seperate?

just need to clear something up.

You roll once for a charge. If you roll a 1 or do not roll a high enough number to reach your target, the charge fails.

As above, it is actually the same roll. You roll for charge distance and if that roll is a one, you will not move (ever, without Might use) and if it is a 6, you get bonus dice in the Combat phase.

Single roll, 2-6 are the distance added, with 6 giving bonus attacks and 1 meaning no charge.

ok, thanks.
