Well, if it's just one battle, then it can be done like this. Astral visit gives experience, air, and +1 spell power. Army: 2 upgraded fairies and a ballista. Attack with hypnosis on the first stack of simple mages -15 mana, and attack 2-3 times. An upgraded mage attacks us; the mages inflict 50% damage on each other, so they can hold out, and in the second round, use hypnosis again to maximize damage. 2 hypnotisms over 3+3 rounds, and the speed of the fairies + the ballista should decide the battle in our favor. It's really very beautiful. Respect to Anton. Added 5 minutes later

Actually, the Moon's starting wall burns for 150 damage, I think ;)
That's why she's so overpowered.

Wall damage = Spell Power * 10 + 10 (basic fire) Moon damage = 3 * 10 + 10 = 40 * 2 (Moon's specialty) = 80 Moreover, her damage cannot be 150 under any circumstances without a fire amplifier. Added 8 minutes later

If you take advanced fire and +1 spell power, the wall will burn for 80.

= (4 * 10 + 20) * 2 = 120 :)
