The Harbinger's blade is very large and roughly triangular in shape, with a large, triangular gap in its center, causing it to resemble a large letter "A". It is predominantly black with red edges. The counterweight is rather large, and is completely grey. The top of its handle is gold, while the rest of it is a smooth, blue-grey rod with a bronze spike set in its pommel. The Harbinger bears a strong resemblance to the Goliath Axe Sword, differing only in color.
A harbinger is someone or something that foreshadows or foretells something else.
The Harbinger's ground combo starts with a quick, one-handed thrust that resembles a guard or block-like motion, followed by a one-handed upward diagonal slash and ends with a powerful, two-handed downward slam.
The aerial combo consists of a two-handed upward slash followed by a powerful, two-handed downward slam.
