As an alternative to Kunai, these Tenno throwing stars do less damage but they come with expanded ammo capacity and a higher rate of fire.
The Hikou is a throwing weapon for the secondary slot, released in Plantilla:Ver. It has a lower base damage than the Kunai and Despair, but a higher fire rate and base magazine size. Like its counterparts, it can also be hard to aim with because of its arrow-like arc projection.
The Hikou can ricochet (rarely) off surfaces, as floors and walls. Ricocheted shots can damage and kill whoever gets in the way.
The Hikou are quite similar to the Kunai, the main difference being about half the damage for twice the fire rate. Regarding this, Hikou are slightly superior, dealing 5 more damage per two thrown, which would equal 1 Kunai in terms for rate of fire. In other words, the Hikou trades a slight DPS upgrade for ammo economy when compared to the Kunai.
As with all thrown sidearms, when performing a Jump Kick your frame will hold the Hikou as dual pistols. Upon hitting the ground and sliding, this will quickly switch back to as it should be.
Hikou (Hikō or 飛行 ) in Japanese means "flight."
The Hikou are based off the Japanese throwing stars from ninjutsu tradition. Throwing stars were primarily used as distractions, and were often called the "invisible blades" due to a thrown star being able to cut enemies unseen from any direction.
The Hikou are the first throwing weapon secondary to receive a prime variant.
The Hikou share at least two common traits with the Kunai and Despair, all three are secondary throwing type weapons, and all weapons have a damage focus mainly on x18px Puncture damage.
