This is the Angel variant of Lord Enma. This enemy has faster attack rate of both Le'boin and Lord Enma, with increased health, attack damage and the ability to raise its attack power by 100% at 50% HP, but the animation is way longer and the range is pretty mediocre too, allowing one of the many units that outranges it, e.g. Salon Cat, to easily demolish it.
12,000 damage (7,200 DPS)
320 (area attack)
10f (50f attack frequency)
29f (11f backswing)
Attack up by 100% when HP is at 50%
The character on Le' Saint's forehead means "Sky/Heaven" in Chinese/Kanji dialect.
