Bolas

Bolas (a.k.a. Bola Shot) is a  skill in Diablo III. Of all Primary skills, it potentially deals most damage, but has a slight delay before impact, giving enemies time to come closer.

In-game
Releases a bunch of bombs that stick to enemies (a monster can have multiple Bolas on it at once) and explode with a small delay for Fire damage to the target and slightly less Fire damage to all nearby enemies (except the main target). Note that even though this skill functions as a missile shot, it does not require a ranged weapon.

Generates Hatred even if it does not hit anything (but only once per shot).

Runes

 * Volatile Explosives: The blast radius of each bola increases to yards.
 * Thunder Ball: The damage type changes to Lightning, and Hatred generation increases to.
 * Freezing Strike: The damage type changes to Cold. The enemies hit by an explosion have a chance to be Frozen for  second.
 * Bitter Pill: The damage type changes to Lightning. In addition, each explosion (not each enemy hit) has a chance to award  Discipline.
 * Imminent Doom: The bolas have an increased capacity for destruction, increasing their damage on applied foes to, and their area damage is increased to against foes within the blast range. This imposes the penalty of  the bola's delay, however.

Trivia

 * In the Demon Hunter class trailer, Bolas were shown in detail close-up: shot from a heavy crossbow, it tangled two red-flashing bombs around a Dark Berserker's neck, detonating shortly afterwards, therefore decapitating the demon.


 * In real life, bolas are a type of primitive throwing weapons, designed to tangle the game's legs and prevent them from escaping hunters.
