Q: When is the destruction or creation of a universe or timeline ranked as Low 2-C (Universe level+)?
A: As the
Tiering System specifies, the
affected area either has to be a large four dimensional space; most commonly, a spacetime
continuum of universal size.
The latter means that
all of the three-dimensional space of the universe has to be destroyed or created, at each moment in time. I.e. the entire timeline has to be destroyed.
Note that only direct destruction or creation qualifies. Just destroying the universe at the beginning of time and the rest vanishing due to the resulting causality paradox does not meet the requirements and would only be ranked as 3-A (Universe level).
For Tiering in regard to creating the Big Bang see
here. Note that for creation feats additional considerations should be taken into account, as explained
here.
A: Whether higher-dimensional entities qualify for such high tiers or not depends on several different factors, which may take root both in and out-of-verse. To explain this situation, we must first clarify what exactly being higher-dimensional entails. In a way, yes, though not how most would...
