- "For if you do it, you will be cursed by time itself. Time will cease to flow over the user, you will be forever unable to die! You will forever be plagued by the deaths of loved ones. To have death avoid you eternally, that is a true living hell..."

- Space-Time Boundlessness
- Space-Time Lock/Seal
User exists outside of time and space and as such are immune to just about anything that would affect or harm them: if time should stop then the user would not be affected. If reality would change, the user would remember both the previous and have knowledge of differences from the old to the new. If the area around the user explodes or the planet which they are on vanish or does not exist any more the user is not affected since they do not exist inside space.

- If the time change happens to change the event in which the user was granted the ability to exist outside time and space (i.e. Omnipresential Attack), then the user may not be immune to the time changes in question.
- Some users still feel temporal changes, even if they are unaffected by them. Such as feeling subjective centuries pass while time is being accelerated but not aging.
- User may be trapped outside of space-time, unable to re-enter it.
- May not be fully aware of the changes in time/time stream.
- Becoming immortal via this method does not negate pain.
- May vary depending on the nature of space-time.
- Power may not work in regions (e.g. another universe) where space-time functions differently.
- User may be anchored to space-time, even if not immersed in it.
- May only exist outside of physical space-time; may still exist within metaphysical space-time.
- If the user moves in and out of space-time, it may be possible to bind them.
- Conceptual Attacks can still affect the user.
