Mission 11 - Revelations | The Main Campaign - walkthrough Castlevania: LoS 2 Guide
Last update: 11 May 2016
After regaining control over your character, get out of the arena and go to the right - you will find a Memorial and Pile of Sacrifice (increasing amount of Dodo Eggs you can carry to 4) there. On the other side of the same room in which you activated the Pile of Sacrifice, you will find a keyhole for a Dungeon Key.
After collecting all the items, it's time to get back to the room in which you activated the Mirror of Fate - it's located close to a nearby Map Room.
Author's note: backtracking (which is basically going through previously visited areas to collect items you couldn't reach earlier because you lacked a skill) is quite irritating in this game and I assumed that no one would want to go back through all those places each time they have unlocked a new skill. I decided to describe the process of backtracking only when you will unlock access to all the skills and areas available in the game - which happens to be right now, after the Zobek fight. If you are interested in finding all the collectibles hidden in the game, go to a section dedicated to this issue. If you don't care about collectibles and you just want to finish the game, ignore this paragraph.
By using the Map Room, get to the Arts District, to engage in the last quest in the game. Go towards the place indicated by the marker on the map (it's close to the place you met Victor and Abbadon for the first time).
Going straight from the street is impossible, that is why you need to use a side alley in which you have found a Memorial (for details head to the description of the 8th mission in this guide). You will encounter Trevor and after a short cutscene you will have to climb up (the route is marked by a purple trail). After arriving at the top the trail will vanish and you will have to jump down and activate the device to operate the Mirror of Fate one last time.
After completing the mirror, go straight ahead to activate a long cutscene. You will be transported on a flying monster's back. At the beginning all you have to do is to climb upwards, avoiding the green explosions. After reaching the top, a short scene will initiate, and after that you will have to avoid the green exploding points again, but this time on foot. Go up (or from your perspective - straight ahead), until you reach giant chains - activate one of them to initiate another cutscene.
After that you will encounter another climbing section - this time you will have to move to the side. The rules are the same - jump in the upper left corner, while avoiding the green explosions, after you reach the back of the monster. You will encounter a group of enemies here, which you can ignore and just go to the right side, to activate another chain an initiate a cutscene leading to a final boss battle.
Boss - Satan
The final boss of the game is a major disappointment if you were looking for any decent challenge. Most of his attacks are unblockable, but he executes them so slowly (and signals the usage of some of them, giving you even more time to react) that they pose no real threat. After fighting with Zobek, this one will really be a child's play.
Again, the most effective tactic is hit & run - get close to him, smack him a few times and jump back. No point in flooding him with your attacks, as he can (and will) block most of them after getting hit a few times. Sometimes the boss will use "an invisible attack" - a black cloud will appear beside him and he will disappear for a brief moment, to reappear near you and attack. It sounds dangerous, but with a little bit of timing you shouldn't have any problems avoiding this attack.
Despite the fact that Satan's attacks are slow, they deal large amounts of damage, so if you generally have a hard time avoiding or blocking enemies, you should consider preparing yourself for that battle by buying all the relics, which may come in handy.
Each time you drop his health down to a certain amount, a scene will initiate and the boss will attack you with ranged attacks for afar. The system works in a similar manner to that of Paladin's - a symbol will appear under your feet and after a short while the place marked by it will explode. The difference is that Satan's explosions occur much faster and there's a black grease-like substance left on the ground for a few seconds, which will damage you upon contact. Avoid standing in the marked places (try to dodge to the side at the last moment) and after a few shots the boss will reappear and the fight will continue.
Satan will "activate" this power a few more times during the encounter, but dodging them isn't really a big problem. Bring his health down to zero to activate a final scene, which will end the fight and the whole game.
