One of my play-by-post characters uses a whip enchanted with the Staff spell (requires once-living material, which leather assuredly is). For tactical reasons, the whip he currently uses is only two yards long, so there are no restrictions on attacking closer targets (except range C for close). I'm finding, however, that he very seldom uses the whip as a weapon (Lightning Whip spell is more effective, and he can cast and maintain a 2-yard Lightning Whip at no fatigue cost). Rather, he mainly uses it as a mage's Staff, to extend his touch range.
Longer whips, in addition to requiring a Ready maneuver after each attack or parry, cannot attack a target at range more than two yards shorter than the whip length. I understand this as a limitation for use of the whip as a weapon, since the popper is the part that can injure an opponent, and it's almost impossible, in real life, to hit a close target hard enough to do injury with the popper of a seven-yard whip. However, in order to deliver a Regular spell by touch, touching the target with any part of the whip (as with a common wood or bone Staff) ought to transfer the magic. Merely touching the target with some part of the whip ought not to be difficult, even if there are multiple yards of additional length extending past the target.
Mechanically, how would I play out "touching" a target at one or two yards with a seven yard whip?
