Lucivar now knew what he needed to do to gain his natural ether and grow stronger.
He only needs to align his intention before killing another person.
If he only defended himself from someone who wanted to kill him, he wouldn't be rewarded.
On the other hand, if he set his intention to kill before killing another person then the rewards are all his. Despite having the bloodline of an Angel, Lucivar was corrupted thus the only way for him to get stronger is through doing what pleases the statues inside of him.
Currently, he only knew two methods, killing intent and also trickery.
Killing intent should please whatever the egg statue was, his Supernatural Ego—while doing trickery, would please Loki. Gaining the gold sphere provided him with the ether to progress to a higher realm while the green sphere expanded his ether reserve.
'It also seemed to increase my mastery...' Lucivar pondered inwardly.
