Assegai of the Steppe-Prince

The Assegai of the Steppe-Prince is a rare weapon that gives a +1 to attack and damage rolls. The assegai has a sleek iron head with a leaf-blade design and a short, dark wood shaft wrapped in braided leather cords. Faint tribal runes etched along the blade’s central ridge shimmer slightly in moonlight or wind. When thrown, it whistles—a keening sound reminiscent of a hawk’s cry.

Boomerang. You can throw the Assegai of the Steppe-Prince as part of the Attack action, it returns to your hand immediately after the attack resolves — whether it hits or misses. 

Windstep Warrior. While wielding this weapon, your movement speed is increased by 10 feet, and opportunity attacks made against you are at disadvantage if you've made a melee weapon attack this turn.

Speardancer's Gambit. When you make a ranged weapon attack with this weapon and hit a creature, you may immediately move up to 10 feet without provoking opportunity attacks. If you then choose to make a melee attack against the same target before the end of your turn, that melee attack has advantage.

Nomadic Instincts. This ability grants the wielder a “sixth sense” as part of being a seasoned veteran hunter or warrior of the steppe. you gain +2 to initiative rolls, and you can’t be surprised while you’re conscious. The weapon grants a faint hum or vibration just before combat breaks out — like the wind whispering that danger is lurking around the corner. 

Fun fact. The use of various types of the assegai was widespread all over Africa and it was the most common weapon used before the introduction of firearms. The Zulu, Xhosa, and other Nguni tribes of South Africa were renowned for their use of the assegai.

Proficiency with a Javelin allows you to add your proficiency bonus to the attack roll for any attack you make with it.
