#3 2Chlorobutanal Sep 28, 2014 22:27:41	No extra cost is required, the initial cost is paid once and changes the spell's effect from "target creature" to "two target creatures."   I would extrapolate that, for a Twinned witch bolt, you may spend your action to deal 1d12 damage to each creature hit by the initial spell.  Thus, a sorcerer who hit twice could spend one action to deal the damage twice, once to each target, each turn.  A sorcerer who hit once could spend his or her action to continue damaging only the "hit" target.  If a target leaves the range of the spell, they can no longer be damaged by the spell, but I would say that a second target (who is still within range) could continue to be affected.   (I'm going by memory of the spell and how I think it should work, as to be honest, witch bolt is a fairly weak spell in my opinion.)

#5 2Chlorobutanal Sep 28, 2014 22:29:48	The concentration part actually isn't an issue.   Twin Spell doesn't make "two spells," it just changes the target of a spell from "1 target" to "2 targets," the same way that upscaling a bless spell into a level 2 spell slot allows it to target two creatures.  Still one spell, one "concentration" effect, but two targets.

#7 FrogReaver Sep 29, 2014 0:38:20	Witchbolt also has a line that the spell ends if the target is out of the spells range.  I'm more interested in how that works with two targets.     It would seem that as written the spell when twinned would either stay on both targets as long as both did not get out of the spells range OR that it would end on both targets if either target leaves its range.   The other possibility that I would prefer to play is that the spell effect ends on a single target when the target is further than the spells range from you.  That's probably how I would play it.  However as written it says the spell the ends and thus as written the spell must surely end and since the same spell is effecting both targets it either keeps effecting them both or stops effecting them both.
