Let's check the math on that:
"Targets: You plus one willing creature per three levels, no two of which can be more than 30 ft. apart"
So we've got V, Blackwing, Roy, Haley, Elan, Belkar, Durkon, Minrah (off-screen).
CL0: "You" - covers both V and Blackwing for free, through Share Spells.
CL3: Roy
CL6: Haley
CL9: Elan
CL12: Belkar
CL15: Durkon
CL18: Minrah
V having a CL of 18 after boosters (like Laurin's Ioun Stone) is not farfetched. So it seems the math checks out.
Belkar was definitely hit by it (panel 3).
