A spell caster can interrupt another caster’s spells by re-channeling their spell back into a ley line. To do this, the caster that wants to re-channel a spell must have access to the color of magic of the spell being cast. The skill to re-channel (“Re-channel”) is Creativity/VH (Default Color-6). The Re-channeler must roll against Re-Channel skill to first identify the spell being cast and then again as a contest of skills against the original roll to cast (by the original caster) to re-channel the spell into the ley line. If successful, the re-channeler takes damage equal to the damage that was incurred casting the spell (natural born casters such as dwarves and elves do not suffer damage when re-channeling magic that they have natural access to). The casting cost of the spell being re-channeled is added to the re-channelers threshold total, but the extra tally from the channeled spell is reduced at a rate of one mana per minute.
I should probably add something here.
