To finish the game and sealing Erazor gjinn in his lamp, first you have to collect at least one ring and dodge his attacks with his purple balls of energy then once he has stopped put your "wii"-mote (lol) in one hand then shake it up and down. Eventually he will come and do a cross beam attack. Dodge it, then he will summon a giant ball of energy and throw it at you and he will say something like "it will take a miracle to dodge my attacks" you don't have to dodge, once he throws it (and by the way fill up you're soul gauge abou 3/4 of the way) use speed break, and you'll push on the energy ball. Here is the tiring part. Shake the remote up and down again to keep the soul gauge from depleting as quickly, then dark sonic will start kicking it like he's on steroids, then it will hit erazor. Fill up the soul gauge to the point where it's orange, then use speed break again in the middle of erazor and you will hit this thing that looks like a giant pimple (lol again) shake the remote up and down again and keep hitting him until sonic (on steroids) punches him a lot. Do this again 3 times, and he will be beat and you go to a clip. ANd a word of advice, on the second and third time you do this, he will use his tail to send out a black "whirlpool" dodge that. ANd something else too. When you see a silver ring, press the 2 button to get it. This is my first post ever, and I hope it helped. Plz comment me on this and advice on what I can do to make my posts bette in the future. Thank u! Have fun gaming!
When you have all 7 World Rings and beat Erazor Djinn or whatever that dudes name is,you can get to the last chapter and turn into the New Super Sonic.When ever you move you gain Soul.Its easy but can get hard if the rings stop coming which will happen,but like Erazor when you first fight him you notice his moves Are how you beat,his motions tell you what move he does.
To beat this boss, you have to shake the wii remote until your soul gauge fills up while dodging his attacks. Wait for him until he attacks with a giant power ball, when he's making it press up on the directional pad to do a speed break. You will block his power ball and you'll have to shake the controller to hit it back to him. After you deflect his attack, you can go up to him and use the homing attack on him. Do this three times and he will lose.
To defeat Erazor Djjin in the second to last mission, you have to run towards him and get as many silver rings as you can. Wait for him to attack when he goes to the left (your left) and strikes down then swipes it through your legs. Instead jump before he swipes his weapon under your feet. This will give you the chance to attack him three times. When he chllenges you to a duel, charge your jump and wait for him to get to the middle then jump and attack.
To get the last world ring you have to beat Erazor Djinn in Night Palace. After you beat him, a clip will show the gate where you put all seven rings. The clip will end and the credits will come out. Go back to night palace and do the new missions in night palace until you get the last ring. When you get the ring, you'll see a new mission called "The Last Chapter" at the bottom.
