The Huaraca is an Inca unique unit available at the Kallanka and the Stronghold starting in the Fortress Age. It is armed with a sling and hurls incendiary stones from a long range. While effective against buildings, artillery, ships and infantry due to their high attack and siege damage, Huaracas are extremely vulnerable to melee attacks due to their poor armor and long reloading time. When fielded in numbers, Huaracas can be particularly deadly.
In the late stages of the game, combined with Kallanka overpopulation, Huaraca can replace Jungle Bowmen as the Incan Skirmisher unit, as they outrange all Skirmisher-type units, deal high siege damage per hit, and can take down enemy artillery relatively quickly. Since they possess little melee attack and negative multipliers against cavalry, they need be surrounded with Macemen at all times.
The Huaraca starts as Elite, but without the increased hit points and attack.
Originally, Huaracas were tagged as Artillery, had 19 range and a ×0.75 ranged attack multiplier against Artillery. With update 3552, Huaracas are no longer tagged as Artillery, have 20 range and a ×1.0 ranged attack multiplier against Artillery.
The standing army of the Inca was formed primarily by nobles, but the Sapa Inca could raise an army of able-bodied men from the general populace at will. Military discipline was strictly enforced when the troops were on the march and the army, although variously specialized, was extremely well trained. They wore cloth armor that breathed well, allowed for free movement, and dissipated the force of blows. Battles tended to open with a hail of projectile weaponry before the forces closed in melee combat. One such ranged weapon was the Huaraca, or sling, which was used to hurl stones with great speed and force over considerable distance. Slings were deadly in the field, their stones capable of shattering bones and causing severe internal bleeding upon impact; their ranged nature also made them an effective tool for attacking defenders while assailing fortifications
