Super Grand Charm

The 'firewall' spell was potent as an elemental attack. The bone warriors were almost killed as soon as they touched. The claw vipers were a little stronger, but they still couldn't last for a few seconds.

That guardian was about to revive the bone warriors again, but the spirit guardian knight flashed beside it and attacked. All of a sudden, no more bone warriors appeared.

The guardian spat out poison and turned the spirit guardian knight green. It was one of a close body attack.

The spirit guardian knight disregarded the damage. Poison didn't affect skeletons as much. It struck its iron sword and after rounds of attacks, knocked the guardian down. 

After losing the guardian who could revive them, all the remaining bone warriors dropped dead under the firewall. Afterward, Abel threw out an 'ice pole' spell and turned the guardian into an ice statue. The spirit guardian knight struck again and turned it into ice blocks.
