Personal Shield Generator

Not to be confused with the first games activated item Shield Generator. Personal Shield Generator is a common item in Risk of Rain 2. It grants the player a 25hp shield that increases by 25hp per stack. The shield recharges faster than the player regenerates health, but won't start charging until damage is avoided for a few second. The amount is displayed on the players health bar, with the right side being max health, and the left remaining health and shields.

It is one of the two items that give you a shield, the other being Transcendence. They are both shown as making the character glow blue when active, with the antennae of Transcendence being the only difference.
