Fire Emblem Heroes - Abyssal Xander LHB Solo Flame Emperor

Flame Emperor can stroll around very much unimpeded on Xander's map, with Xander himself being the only thing that can deal significant damage to her, and only then just for the single turn he can have his special charged. It's not hard at all to clear the enemies around and have the larger area in the middle remain very empty outside of the boss, and quickly dispatch everything by turn 5. Enjoy the clear!
