Golden Axe II/Ruins

Head to the right. Take out the Red Heninger and Longmoan and continue to the right. After this a Red Wizard and Longmoan will attack you, the Wizard riding a Chicken Leg. Take the Wizard out and grab the Chicken Leg.

In the next area you'll find two magic books on the ground and also the first three Skeletons. If you go slowly you will only fight one or two at a time. The ones on the ground really are dead and won't bother you.

After this you'll fight two Grey Wizards followed by three Grey Skeletons. Again, take your time and only one will appear at a time.

Boss battle
In the next area you'll fight two Grey Skeletons followed by three Pink Skeletons. After this a Suit of Armor and two White Skeletons will appear. Use all your magic here.

If you still have the Chicken Leg you may find it unsuitable for this battle. Its tail attack is fairly slow; to hit him with it you have to face away from him before attacking. Because he can dodge the dash attacks aren't very useful either.

Bonus Stage
Three snails will crawl onto the screen and turn into Wizards (two Red, one Green). The Red Wizards drop a total of three magic books while the Green Wizard drops some food.
