Instructions
Dodge Iblis's flaming rock attacks by jumping to a nearby floating block of land. You can also time your jumps to leap above the flaming rocks and land back on the same floating block of land.
Collect the rings on the surrounding blocks of land to increase your health and replenish it if you have been hit by Iblis's attacks.
Wait for Iblis to do a tremor attack, which will shake blocks of land out of the sky. Once these additional blocks fall, follow them to the crystals and press "A" twice on the Xbox 360 controller or "X" twice on the PS3 controller to do a mid-air dash against the crystals, which will light them up.
Wait for Iblis to become attracted to the crystals, then perform a mid-air dash when he is near enough for you to break the green diamond on his forehead. Repeat the process four times to defeat Iblis.
