Bead of Force: Prison or Sanctuary?

[TheApapalypse]

After it is thrown up to 60ft and explodes for 5d6 damage it encloses 'a' creature in a 10x10 sphere that cannot be harmed for 10 minutes...

Is this a bead thrown at a street urchin surrounded by wolves giving you time to pick them off...
Or a bead thrown at a boss protected by underlings giving you time to pick them off?

You will probably kill the urchin, and you hope that there aren't any wolves adjacent to him. I would only use it as a defensive measure for targets as long as I was sure they would survive the initial blast.

So you interpret that the blast occurs/centers on the target....why would I hope there are no wolves though? Wouldn't the force blast weaken if not kill them?

I don't see any other sensible way of interpreting "all creatures within a 10' radius". That's the same sort of wording they use for all other blast spells and nothing in any source indicates that a central point or square is exempt from the effect.

If the wolves are adjacent to the target, they will also be on the inside of the sphere. 10'radius, remember. Said urchin will be dead from the damage and any adjacent wolves, if they survive, will be eating his corpse in peace, immune to any damage from the outside.
