My code is working fine but when the big ogres come I die. Here’s my code:

# Defeat as many ogres as you can.
# Use 'cast' and 'canCast' for spells.
while True:
    enemy = hero.findNearestEnemy()
    if not enemy and hero.canCast("regen", hero):
        hero.cast("regen", hero)
    if enemy and enemy.type != "catapult":
        if hero.canCast("lightning-bolt", enemy):
            hero.cast("lightning-bolt", enemy)
        elif hero.canCast("chain-lightning", enemy):
            hero.cast("chain-lightning", enemy)
        elif hero.canCast("root", enemy) and hero.distanceTo(enemy)>5:
            hero.cast("root", enemy)
            hero.attack(enemy)
        elif not enemy and hero.canCast("regen", hero):
            hero.cast("regen", hero)
    else:
        if enemy:
            hero.say("C'mon! Move you stupid catapult!")
            hero.say("C'mon!")
            hero.moveXY(hero.pos.x+20, hero.pos.y)
            hero.cast("lightning-bolt", enemy)
            hero.moveXY(hero.pos.x-20, hero.pos.y)

I manage to get about 32 kills but then the big orges come and kill me.

Try going to the grey circle when you see the big ogres.

When you find the catapults, move around and back, the catapults will kill the ogres with their missiles, which will then cause a chain reaction of fire traps to kill the catapults.

wait…finally! I got 44 of them! I went to the grey circle and yes, the circle made everything explode!
