When she said additional skill, it could be said that it was two skills rather than just one since the skill had two effects. One that activated on different conditions.
The first activation condition was that she needed to be in a demi god form.
For the second activation condition, it was that she needed to enter her god form.
[Divine Presence – Divinity of Nanobots]
Demi god Activation – When activated in Demi God form, you bring out the maximum potential of your divinity during that period of time, anything and everything can be turned into nanobots, including living beings. Anyone who does not have a resistance towards divinity is suppressed by you and depending on the difference in strength, they will be eliminated immediately should you decide to convert their entire body into nanobots.
Duration – This lasts until your demi god form runs out. Can be turned off manually.
Cost – N/A
