Those two spells looked great, but they failed to be attractive in actual (competitive) play. This suggestion could change that, and i was irritated that this wasn't the mechanic in the first place: Lower the requirement for targeting, enable to target multiple characters even when one or two of them arent in the line of sight of your caster. As long as the conditions for distance are fullfilled (within 2 squares, 3 squares), allow them to be attacked indirectly through the "conductor", the first, visible target.
To "fix it up right," it would need to be that there is one target, and characters with clear LoS to the target within X squares are affected. Otherwise you could have a character in one room targeted, and another character in an entirely different room be hit through the wall.
Yes. You only choose the first target, then it jumps to the closest char (within 3 tiles) then the closest char to that one (which may be the first target). Can't jump through Blocked terrain, but can jump through Impassible, Smoke, and Illusion. Mouseover the first target to see the other targets (like we already do with Bungled Heal).
