If needed, moving to where I can catch the most possible enemies, particularly the minions, into a close blast 3, then using Thunderwave to target the most possible enemies.
Multiple attack rolls (up to 9 targets):
Attack1 vs. Fortitude - (1d20+7)[22]
Attack2 vs. Fortitude - (1d20+7)[24]
Attack3 vs. Fortitude - (1d20+7)[16]
Attack4 vs. Fortitude - (1d20+7)[20]
Attack5 vs. Fortitude - (1d20+7)[22]
Attack6 vs. Fortitude - (1d20+7)[22]
Attack7 vs. Fortitude - (1d20+7)[27]
Attack8 vs. Fortitude - (1d20+7)[13]
Attack9 vs. Fortitude - (1d20+7)[23]
Damage on hit - (1d6+5)[6] and push 1
Map would really be helpful here so I can actually know who and what I'm attacking...
