4320 Target: Enemy Base Skill: Eclipse
Envelop yourself in a lightless sphere for 10 seconds to protect yourself. Anytime you take Direct Damage, the sphere lashes back at the attacker, reducing their movement speed by 40% for 3 seconds and healing you for 2066 Health. These effects can occur once every half second.

Unstable Core is a morph of the Eclipse base skill. The other morph is Living Dark.
