If we ever manage to unlock the Dao of Primordial Chaos, what would it's actual capabilities be? Here's my theory but do tell your's-
Since LB said "chaos cannot be shaped and cannot restrained. It does not have limits". I will take her words into consideration while adding some of my own ideas.
Since Chaos Dao is essentially the sum and origin of all other daos, I think it could allow us to use every dao without training in them. This would be my favourite ability like imagine switching daos so fast that you just essentially chain combos, Using Dao of Light, the Dao of Time, the Dao of Causality etc. We have actually seen a single dao being able to replicate other dao from the lyrical veil Dong Guy that we fight in the free for all that could simulate wind and time dao using the song dao.
Since Chaos Dao is transcends every other dao, It would possess a inherent superiority that basically makes it win even against an more developed dao. Basically if you stop time with Chaos Dao, Even a significantly more skilled time dao practitoner wouldn't be able to cancel the time stop unless the difference in skill is utterly absurd.
Since Chaos Dao is Limitless, You can just keep increasing your stats and spell power infinitely without limits, even at God Stage, meaning your potential is infinite.
Since Chaos Dao cannot be restrained, No one can seal your Dao or Body and suppression just doesn't work on you.
Since Chaos cannot be Shaped, The Chaos Dao would allow to turn into a formless mass of Chaos that can take any shape. This would differ from a Dao of Water or Wind due to the fact that the Chaos assimilates anything it touches.
