Brass Contraption

The  is a bell-like airborne monster introduced in Risk of Rain 2.

Skill & Behavior
Brass Contraptions float steadily in the air and pursue targets slowly.

Any single instance of damage that deals more than 10% of the Brass Contraption's total health will stun it and interrupt its attacks or movement.

Primary: Spiked Multishot
The Brass Contraption's only attack is to summon 3 spiked balls above itself heralded by a clanging sound, which lasts 2 seconds (scales with attack speed). It hurls the balls at its target one after another over 3 seconds, which also scales with attack speed. Each spike ball travels at 80 m/s and deals 500% damage with a proc coefficient of 1.0. They also stick in the ground for 6 seconds, but this is cosmetic; they will not deal any damage if touched.

This skill has a 5 second cooldown.

Behaviors

 * 1) Use primary and flee: the Brass Contraption must be within 25m from its target. The primary isn't necessary to be off cooldown. This behavior will be active for 0.5 seconds.
 * 2) Use primary and strafe: the Brass Contraption must be within 25-50m from its target. This behavior will be active for 1 second.
 * 3) Chase: no requirements.

Tips

 * It's recommended when fighting Brass Contraptions to always strafe around them clockwise. Since Brass Contraptions always fire the spike balls from their right to left, moving this way will make avoiding the last two shots easier.
 * The Brass Contraption's spike balls travel quickly, are deadly accurate, and deal heavy damage. Players must remain vigilant to avoid being blindsided or struck from a long distance.
 * Being stunned, frozen, or shocked only prevents a Brass Contraption from summoning new spike balls; if it already has prepared them when it is afflicted by the status, the spike balls will be launched regardless.

Trivia

 * Brass Contraptions have several unused behaviors:
 * The spike balls have unused behavior where they explode on impact with a radius of 6m, dealing 100% damage with a proc coefficient of 1.0 with sweet spot falloff. After exploding, the spike ball would spawn 4 tiny spike balls.
 * There is a spike ball projectile named "bellDevice" which is larger and rounder, with similar properties to the spike ball that is currently used.
 * There is an unused entity state for the Brass Contraption in which it would aim a beam at a nearby ally and grant them invincibility, which would wear off when the Brass Contraption died.
 * In the game's credits, a sketch of a Brass Contraption shooting a laser from its bell appears. It is possible that this behavior was the original attack of the Brass Contraption and was changed later in development.
