Beetle Queen

The Beetle Queen is a new Boss Monster introduced in Risk of Rain 2.

She shoots acid in a cone shape, leaving behind puddles of acid. The inital hit has a Proc Coefficient of 1.0, whereas the lingering acid pools have a Proc Coefficient of 0.1.

She also periodically spawns 3 beetles.

When her health is below 50% she spawns flying beetles that inflict the beetlejuice debuff, a stacking debuff reducing most stats.

Drops
The Beetle Queen has an associated Boss item. Upon defeating a Beetle Queen summoned by a Teleporter Event, this item may drop as a reward.
