Stage 14 (The Necromancer): The battle with Sauron | Walkthrough LEGO The Hobbit Guide
Last update: 11 May 2016
The battle with Sauron is definitely the most demanding of all the boss battles, which you have already dealt with. It is very easy to lose all your health here and, additionally, you may have difficulties figuring out the right pattern. Spend some time on learning the boss's attacks. dodge from the violet and blue projectiles that he fires, by remaining in constant movement and by dodging.
Later into the battle, there will appear the regular orcs around. Just like in the case of the recent battle with Azog, try to ignore them (frequent jumps and incessant running), especially that you might miss Sauron's next powerful attack and lose more than you could gain.
Continue avoiding Sauron's attack and wait for the moment in which he tries to pepper your characters with a hail of blue projectiles. Stop then in one spot and press the key/button displayed on the screen, which will form a force field (screenshot 1). This is not it, because you now need to press the action key/button several times (screen 2).
Performance of the above actions will result in the appearance of interactive bricks, in of the areas of the arena. Run up to them, quickly and hold down the appropriate key/button to start building another tower.
Important note - the building process, in this case, cannot be interrupted by the regular orcs so, do not worry if, in the meantime, they will stand near your character.
This is not it, however, because in the initial part of this stage, you need to send a magic projectile towards the recently built tower. This will send out a stream of powerful energy towards the boss (the above screenshot).
Later into the battle, you need to repeat all of the above steps. Therefore, you should wait for an opportunity to deploy the force fields and build towers. Then, shoot the magic projectiles at them, using the staff. You need to build, and activate, three such towers, thanks to which the battle with Sauron will draw to an end.
