It seems she means that Amku could have been killed and other non-damage spells used.
Do you mean they could have killed him and used other non-damage spells?
Rimp, then it's even easier. If it's just a coincidence and Amku's world has no non-damage spells (which is already a lot for 1-2 heroes without non-damage spells for a city), then you can attack from Amku-Mould-Dracosh any unit. But Amku is definitely a ranged attacker.
