Getting to Assiel | 9: Devil Inside DMC: Devil May Cry Guide
Last update: 11 May 2016
After a conversation with Phineas move forward, following the path. After reaching the end of a shelf stay in front of a red part of the wall and use an Arbiter to destroy it.
Start exploring corridors. I recommend to stop where the screen above shows, at grapevine. Destroy it with Osiris, enter new room and free a Lost Soul. After that resume marching. A moment later you'll meet Phineas again.
Now you have to jump onto platforms beneath you. Use double jump and Angel Boost every time to be sure, you won't fall into abyss.
After reaching the big wing, you will fight the Witch for the first time. During battles with them I recommend to be careful, because they have various attacks, can cause huge damage and you not always can hurt them. Focus on avoiding standard Witch's attacks (screen above) still moving and making evades.
Witch's second attack is to throw a demonic blade at you. Also in this case you can evade it but it is better to throw the blade away. When you notice that it appears over the Witch, hold it with a Demon Pull and when it's pulled to Dante bounce it to hit a monster.
When it comes to attacking Witches, the main difficulty lies in their force field. You can deal with that on two ways. First one is to bouncing their demonic blades. The other one requires attacking them with angelic weapons (like Osiris). When the field is down, use your strongest attacks.
After battle find a latch and use Angel Lift. Be careful, because you will be forced to use quickly Demon and Angel Lift in one place (screen above). Continue until you reach a new part of a wing.
Jump onto next platforms using Angel Boost if necessary. In the further part of travel you will have to use Angel Lift again. Be careful at the second time, because you'll catch a Boost Ring (screen above). It means that you have to remember about pressing a jump button. Wait until Dante gets artifact and will be moved to the Dreamworld.
