Sinspawn Gui is comprised of four parts: two arms, the head, and the main body. The main body is the actual boss and bringing its HP down to zero will complete the battle. The problem comes with the arms deflecting physical attacks to the main body, so you will have to take care of those before anything else. Of course, the arms don’t stay away permanently, as they will come back and there’s nothing you can do about that. The arms don’t attack at all, thankfully, but they are armored, so you will have to use either Auron, Kimahri or Lulu’s magic to defeat them.

Bringing the attention to the head, it can use Thunder on a single character, which isn’t that big of a deal, but you can use NulShock to protect against it if you want. The bigger problem with the head comes when it starts moving suspiciously. That means on its next turn, it will use Venom, which does physical damage to a single character, as well as inflict Poison. However, you can stop this by attacking the head, but it’s only reachable with ranged attacks, like Wakka’s normal strike, Lulu’s magic or Kimahri’s Lancet. Just a single hit is more than enough to make the head stop shaking.

The head should be your first target and when you’ve depleted its health, the head will turn gray in color. Your next target will be the arms, but it’s best to either let Auron/Kimahri handle those, or blast them with Lulu’s magic. That will leave the body alone for a little bit, but it will attack you. The body can either do a physical attack that hurts quite a bit (600 or so damage), or Demi. You might remember the Demi from Sinspawn Ammes, which doesn’t actually kill you, but the danger of the normal attack means you should heal. The body should alternate between the two, but might skip the physical when it’s lower on health. When the arms show up again, take them out, then continue eating away at the body’s HP.

Second Battle

The second battle against Sinspawn Gui (takes place right after the first) is a lot easier, despite you only having Yuna and Auron from your party, since you also have Seymour. He has access to the second tier of Black Magic, as well as Cura, should you ever need it. The battle’s less challenging, too, since Sinspawn Gui has less health than the first version. The head, as before, should be the first thing taken out, with one spell from Seymour likely taking it down, since it only has 1,000 HP. From there, take out the arms as usual, then begin working on the main body. It’s essentially the same fight, but much easier due to Seymour. You should have a much easier time for an Overkill if you use Seymour to finish it off for good.
