Magic Bullet is a tier 4 skill in Aurelia's The Huntress skill tree. This skill grants Aurelia health regeneration for a few seconds every time she scores a critical hit with a sniper rifle. The shot also creates a healing nova centered at the target.
Heath Regeneration: Up to 7.5% of Max Health / sec
Healing Nova: Up to 25% of Max Health
Regeneration effect lasts 10 seconds.
The healing novas also affect Aurelia, and can revive downed characters, but the radius is fairly small.
