Though Kieran killed several of the Chimeric and Deranged Homunculi with his previous use of Dread Culling, with the skill not triggering the culling cooldown reduction effect, he noticed that the rapid reactivation of the skill led to him discovering some in-depth intricacies about his skills.
For example, though the Dread Circlet appeared somewhat sentient by the way it immediately latched on to his attack, provided that it followed the guidelines of the skill, it wasn't.
Instead, there was some strange principle governing this skill. As he focused on this sensation, Kieran learned that the principle was linked to a desire. Not a desire that came from him, but a desire born directly from the Dread Culling's Source Rune.
