The first phase of the battle is rather simple. Just run around the outer edge of the
circular platform that you are standing on, being careful not to get too close, causing
the boss to smack you. Stagnox will slowly turn as well, but will eventually stop to try
to attack you using an incredibly slow horn thrust that looks quite impressive, but it is
extremely easy to avoid. When Stagnox misses its attack, quick run to its backside and
pull out the whirlwind. Target the purple fog and send a gust out of the whirlwind and
this will stun Stagnox and leave its backside vulnerable. Run up and slash at its backside
repeatedly until it gets back up on its feet. Repeat this same process a few times and
just keep striking at its backside.
Eventually Stagnox will give up on this failed strategy and will then use its wings and
fly up in the air. Stagnox will summon three blastworms and toss them down to the battle
platform. Slash at these three slugs to turn them into spiked balls. After a few moments,
Stagnox will try to hit Link with a flying thrust as he drops down closer to the platform.
Stand below a spiked ball and when Stagnox is coming towards you, use the whirlwind to
send the blastworm right in the boss's face. The explosion will stun Stagnox and leave his
backside vulnerable yet again (he really needs to work on that huh) giving you the perfect
opportunity to run over and slash away at its purple spot. Repeat this same process until
Stagnox has been defeated.
