The highest priority of the god of illusion right now is living. Since half bread is better than none, he was willing to give up control of his body so that at least one of his souls would survive as a half god.
The virtual body had destroyed six outer bodies in a short amount of time, leaving three more. These three outer bodies separated from his body, transformed into avatars, and ran away from the true body.
The three avatars scattered in various directions, but even this failed because the virtual body used the Mental Domination divine ability to attack the three avatars while still attacking the virtual body.
This wasn't the dream realm where their enemy had the home ground advantage and used a divine ability for escaping. This was the physical world where tricks couldn't be made. Plus, they had their virtual body here, not just a copy of their mind made through the Mind Domination divine ability.
