[IC] Chapter 1-9: Circle of Hate

[DM Surranó]

OOC - Range is a limitation on point of origin as well as on the spell's area of effect.

If any portion of the spell’s area would extend beyond this range, that area is wasted.

i.e. a spell centered on you with radius 20' must have a range of 20'.
Note that the spell's effect, once in place, is a different topic. E.g. you can summon a creature at the edge of the range and it can move farther but I'm not sure you can still control it unless you get within range to them again.
