Interesting boss, a thing you can do since I didn't do it in this video, because I didn't bother to try hitting it with any other element besides wind. But if you hit it with water it can reduce his STR stat, you can also hit with fire and it turns his normal attacks to deal fire damage.
I got wrecked by his SP attack the first time I fought him, so I came better prepared to deal with the earth and fire damage. If you hit it with water enough times you probably can get it to a point where it doesn't do a ton of damage.
If you play luna neko, the tiger luna neko armour conveniently protects against earth and fire and it's also an FD armour. Fortunately I had another armour I could use although it's FO but it protects against earth and fire decently well and I also used the mountain's talon tower shield.
