the Cause fear The spell states the following about the update (emphasis mine):
When you cast this spell using a spell slot of level 2 or higher, you can target an additional creature for each level of the slot above the 1st. Creatures should be at a distance of 30 feet from each other when you point them.
Other spells, like Lovely person, they have identical limitations in upcasting. If you cast a spell of this type on the 3rd level (that is, on up to 3 targets), can you chain the spell so that each target is within 30 feet of another target, but two of them are not within 30 feet of each other?
Visualization (X = objectives):
X <--30ft--> X <--30ft--> X ^ ---------- 65ft ----------- ^
Would this satisfy the condition given by the spell?
