Last night during a game session, one of the players cast Bless, and requested to target himself as well as 2 party members. On review of the PHB for spell casting and ranges, it was not specified if the caster counts as a valid target for a non-self spell. It did mention cone and line spells that originated from the caster (as in targeting a point at the casters location and emanating out from there), but made no such distinction for ranged spells.
I ruled that the caster was not a valid target, as the range was not self, but now I'm not so sure.
Is the caster of a ranged spell such as Bless considered a valid target (creature in range)?
