Sword Spirit is a boss bird spirit that appears in Old Nesting Burrows - 4. This legend's power too powerful, it places the Mighty Eagle sword in the stone, and defies the time to challenge the Flock in that level.
It guards itself well with Avenger, Dragontooth, and Dragonscale, but gets Knight's ability. Its power is also too powerful it even prevents potions from being used, and he challenges with only one other bird.
- Before update ?, he did not get the set item combo, making him less threatening.
