Blood Soaked Shields

 is one of Gaige's Tier Two Ordered Chaos skills, which causes her to forfeit a sliver of health to recharge her shields whenever she kills an enemy.

Effect
With this skill, killing an enemy will immediately recharge 20% of Gaige's shields, but subtract 1% of her health in the process. If Gaige's shields are full, this effect does not trigger, and Gaige will not lose health.

To illustrate: 1% of 500 health is only 5 points. This does not seem like much, but this effect will trigger every time Gaige kills an enemy while her shields are partially or completely drained. The lower Gaige's health is while her shields are depleted, the riskier this skill becomes.
