This fiery knight Heartless's skillful defense makes it tough to finish off. Though its focused slash can be stopped with a block, blasting the knight with Blizzaga while it is storing up energy will stagger it, opening it up to extra damage.

Strategy
The Heat Saber is by no means an easy opponent to defeat; luckily, you are accompanied by Xion and Axel to help you take it down. It uses the element of Fire in its slash attacks, so equipping the Fire Charm or even the Tears of Flame would be greatly assistful. After a combo by the Heat Saber, the Heartless will stay still for a small period of time; at this time, attack with Blizzard magic, as this is not only the only type of attack magic that it is affected by, but also its weakness. Continue in the pattern of dodging the Heat Saber's combo and using Blizzard magic while it pauses, and this Heartless should fall. Also, attacking this Heartless while it is storing energy will cause it to immediately perform its focused slash.
