To attack roll 3d6 and SUBSTRACT them to your OCV + 11 + combat skill levels you put in your attack (per type) if you have any.<br/>That will give you the DCV of the target you aim to get.<br/><br/>Example : if your OCV is 6 and you have 2 skill level in HTH, and, and you roll a 10 on 3d6, the math would be :<br/>6 + 11 +2 - 10 = 9 (so you'd hit a DCV 9)
