Vizier Fight
When the battle begins in the arena, he'll charge at you. Simply dodge the boss by rolling to the side. Eventually, the boss will levitate and throw large pieces of stone debris. Again, evade the attack by side rolling. Get close and hit the boss a few times if it tires out.
After this phase, the boss will summon a large sand twister that can kill you. The prince needs to seek out a pillar at the edge of the arena that lets him wall run vertically and execute a speed kill. Do the displayed commands to cut off the boss' wings.
For the final phase, the boss floats high off the ground, and the prince will be forced to do a series of jumps, leaps, and siddles on the floating stones to reach the boss. The boss will try to shoot you down with an energy blast, so time your own jumps to have something obstructing the boss' line of sight. When you get close to the boss, the prince should begin executing the last and final speed-kill.
