Hardlight Afterburner

Hardlight Afterburner is a new rare item in Risk of Rain 2. It adds 2 charges to your Utility skill per stack, and reduces its cooldown by 33%. It greatly increases mobility and is visually shown as two purple afterburners protruding form the characters shoulders.

However, some caveats apply; Mercenary's Blinding Assault can be chained 9 times, but will still immediately go into cooldown if you miss an enemy.

As the Engineer, throwing around multiple Bubble Shields may make it difficult to fight as each of them could block your shots. However, a shield will be ready for you to deploy immediately after the previous one expires.
