Naturally, the reason Owen had been able to fuse his god skills this time so smoothly was primarily because of the deep understanding and insight he already possessed regarding god skills.
It was only thanks to the new perspective Heller provided that Owen managed to complete the fusion with such ease.
Even though the other gods present had now realized that god skills could indeed be fused—and that such fusion would result in an explosive increase in power—most of them were still unable to reach that threshold.
After all, the foundation of a fusion was the depth of one's god skill mastery.
As a 2-star Peak Ancient God, Owen's foundations surpassed all the gods present by far. He also had support from powerful artifacts like the Core Crystal and his recent breakthroughs in the Realm of Immortality.
