Costume Quest

The last thing you do in the game is fight Araxia. You'll need to help every type of monster and get through their main gate to get to Araxia. The fight is the hardest fight in the DLC and possibly the entire game without proper strategy but lucky for you I'll tell you the strategy that makes you almost invincible.

First thing's first and that's the costumes you're going to use. You're going to be using the robot and yeti costumes for sure but the third costume is up to you. I personally used the ninja for some extra attack power but you could also use the unicorn for healing purposes though you shouldn't need to heal at all. Now onto the stamps. For the robot use the Skeleton of the Wolf stamp since he's your main attack and it doubles his attack power. For the yeti use Galvanized Mummy Gauze because with this on he hardly gets hurt. You'll need the yeti to stay alive because his special ability is extremely important in this battle but I'll get to that later. On the ninja/unicorn use Multi-Winged Vampire Bat as your party's healing source. You'll gain enough health from this stamp that you shouldn't need a healing costume but if you want to stay on the safe side you can use one.

Now onto the battle strategy. You'll be fighting both Araxia and Big Bones in this battle. Big Bones doesn't attack every turn however. Once a piece of candy drops into his mouth he'll be reenergized and he'll attack you on his next turn. His attack does devastating damage to the entire party but that's where the yeti comes in. Use the yeti's special ability to protect the entire party and basically nullify his attack. Now that you know how to survive Big Bone's attack you'll only need to worry about Araxia.

Araxia doesn't have any powerful attacks and he does the same attack over and over. His attack isn't that strong so it isn't anything to worry about. Every 1000 HP or so he'll fly up in there air. Your attacks won't do any damage to him when he's in this state but every time you hit him he'll fly backwards. Hit him 3 times and he'll get hit into Big Bones and when he lands he'll be able to get hit again. Keep attacking him and you'll be good to go. Near the end of the battle he'll stop flying up and instead he'll heal himself. If you have all of your party members still (which you should, you're practically invincible) you can make quick work of him. Once you defeat Araxia you'll win the battle and you'll earn your trophy.
