The Legend of Zelda: Skyward Sword HD brought back the nasty giant spider from the Skyview Temple. To kill the Skulltula spider in Skyward Sword, you need to hit the weak spot in their abdomen.
This requires you to cut the cut in a specific way to make them flip or spin around. However, letting these giant spiders expose their weaknesses is where things get a little tricky.
To expose their Weaknesses, you need to attack them in a specific way to make them vulnerable. If the spider is hung on the string, you must do a horizontal slash. This should expose its weakness, allowing you to pierce the sword into it and damage the Skulltula.
However, sometimes you cannot hit the weakness with a thrust attack. If the spur attack does not work, Skyward Strike will definitely work.
But what about those Skulltula that don’t hang from the ceiling? Well, in this case, you have to flip the crawling spider and expose its weakness, you need to make an upward slash. The attack should knock down the giant spider, knock it down on the back and expose the weakness.
You can now kill exposed Skulltula by launching a critical blow. All the Skulltulas in the game are pretty easily to defeat if you follow these steps.
