Wild Arms - Sado

The final of the bosses we need to fight for gear is Sado, who is in Malduke. If you've dealt with Lucifer already, this isn't something you haven't seen before. Play the guitar in the magic circle/altar thing and he will appear and attack. Take him down to get Rudy's ultimate armor.

Due to how brief the video is, you can see there just isn't much here. The same strategy as Lucifer and Boomerang Flash, and since this guy is squishier, he bites the dust faster than either of the other two.
