I see that Chill Touch allows you to affect several creatures, but it has a duration of instantaenous. Does that mean that a 10th level caster could affect up to 10 creatures at the same round he casts the spell (if he could reach and touch them all, that is). Or does that mean that a 10th level caster could affect 10 creatures over as many rounds as it takes, and if so when would the spell wear off? Any help would be appreciated, thanks guys!
