Lightning Palm (Or non-cheeseball name)
Damage - 7
RoF - 1.5 (Or hell, even a slightly slower one due to charge up would work)
Spread - Linear pulse, instantly hits and reaches end of range on use
Clip - lowest possible (Or alternative with description below)
Basically you shoot lightning out of your hands that hits in a linear path. Hopefully it'd be able to sap some health from the player (2?). In exchange, have it slow or set a player on fire. Maybe add in a little charge time in order for it to be compensated for said ability. Similar to a no-clip weapon except that it has a fairly short range and will hit all players instantly in its path when charge is finished so it will not have a charge time. Hell, maybe even give it ramp-up. Give or take what you will.
