Hi, in the section on crossbows in the Equipment Guide and Fantasy Hero it mentions that crossbows are built with a 0-point version of concentration where the character is only at 1/2 DCV for loading it, the limitation having been reduced by -1/4 from its original -1/4 for 1/2 DCV. My question is, what guidelines did the author follow to get to this 0-point version of concentration? The author seems to have applied a limitation to a limitation but I can't find anything on applying limitations to limitations in the core rules. To make things even more confusing the crossbow and other muscle-powered weapons requiring concentration use a -1/2 concentration limitation in the core rules. Can anyone help me out here? Apologies if I'm not making myself clear.
