The Octiron has a peculiar, cross-like shape, with its blade split into two pieces. The middle blade is long, with a wide, flat tip and concave sides. The side blade fans out and sports two circular notches in its outer edge. The counterweight is of a similar shape and size to the side blade, though a bit smaller and lacking the notches. Both blades and the counterweight are black with indigo edges. The three blades are connected by a thick, white cross with red edges attached to the handle. The top tip of the handle is rust-colored and the pommel is decorated by a spike of the same color, while the rest of the handle is black. This Axe Sword is identical in shape to both the Copper Red and the Iron Black, only sporting a different coloration.
Octiron is a fictional metal from the Discworld series, which is used to construct the most magical of artifacts.
The Octiron's normal ground combo starts with a two-handed downward slash, followed by Lexaeus leaping into the air while performing an upward slash, and ends with a powerful, two-handed downward slam. The -Combo can be activated after the first downward slash, and consists of a leap with an upward slash, followed by a powerful, one-handed downward slam before ending with a fast, 360-degree spinning attack.
The aerial combo consists of a two-handed upward slash and a one-handed sideways swipe.
