Non-Omnipotent complete arsenal is like power with multiple restrictions like it might be limited toward superpower/supernatural/below any phenomenon power or any power that is that is not basic.

So it's like have complete set of basic/average power.

But Nigh-Omnipotent basically have every power but at some power they have limitation on it like how much power they can use or like at what level they can or how much they can use. It like everything but having one restriction that is there existence.

But remember this if nigh-omnipotent Transcendence out totality and become absolute Transcendence being then they're free from restriction and they can use any power without any restriction. Plus point nigh Omnipotent don't have much authority over everything.

@Unknownpotency Very interesting! That is certainly an unique take.

Thankyou.

@Unknownpotency You're welcome!

Non-Omnipotent Complete Arsenal possesses absolutely every ability, but at a non-omnipotent scale (that the majority opinion seems to be that omnipotence is greater than absolute, so absolute abilities are still fine). This would include Nigh-Omnipotent versions of anything like Arcanepotence, Scientiapotence, etc.

Nigh-Complete Arsenal possesses nearly all abilities, or all abilities related to/within a particular domain. For example, they might possess all powers except variations of Selective Omnipotence, or all non-absolute abilities, or they might possess all magical powers, or they might possess all abilities from a particular reality/universe. For example, the embodiment of a particular reality would reasonably possess all powers and abilities that exist within that reality, as by definition, they would all be aspects of the embodiment.

Thinking about it, in principle, there is nothing to say you couldn't have a Nigh-Complete Arsenal that includes omnipotent-level abilities, so long as the user is themselves Omnipotent. For example, a user of Arcanepotence might possess absolutely all magical abilities, including ones on an omnipotent scale.

@AzQth I see. :)
