Level One (25 or Less Alteration)
The initial form of Astral Projection. The Practitioner is very weak and unskilled at this Level, and can only maintain their connection to their Physical Body over a short distance. At this Level, the Player cannot interact with the Physical World in any meaningful way-- they cannot open Doors or use Activators.
If the Player moves too far from their Physical Body they will instantly be forcefully returned to their Physical Body, ending their Astral Projection.

Level Two (25 - 49 Alteration)
At this Level, the Practitioner gains the ability to travel an infinite distance from their Physical Body. They are still unable to interact with Doors or Activators.

Level Three (49 - 74 Alteration)
The Practitioner is growing more confident in their Astral Abilities, and is now able to briefly manifest on the Physical Plane just long enough for minor interactions with the world around them. At this Level, the Player can use most Doors and Activators, greatly expanding the range of their Astral Projection abilities.
The speed at which you shift between Planes is increased.

Level Four (75 - 99 Alteration)
Reaching Level Four grants the Practitioner the ability to briefly manifest on the Physical Plane long enough to make themselves visible to others. At this Level, the Player is able to speak to NPCs, but is unable to Pickpocket or Loot them. This does not affect their ability to remain undetected whilst on the Astral Plane.

Level Five (100 or Greater Alteration)
At this Level the Practitioner has mastered Astral Projection. In addition to all previous bonuses, the Player can now choose to Summon Physical Body when returning to the Physical Plane, allowing them to bring their Physical Body to their present location, rather than returning to where they previously where.
You can now shift between Planes much faster.

Travelling on the Astral Plane is difficult and wearisome, and therefore the Player can only remain on the Astral Plane for a short period of time. When you begin Astral Projecting, your Magicka Meter becomes your Astral Meter, and will continually drain for the duration of your Astral Projection. Regardless of your Astral Projection Level, if the Astral/Magicka Meter reaches zero, you will instantly be drawn back to your Physical Body.

Obtaining the Alteration Skill Perk, Stability, will reduce the rate at which the Astral/Magicka Meter decreases by 50%, doubling the time you can spend on the Astral Plane.

There are several ‘issues’ caused by the way Skyrim works which have a minor negative impact on your Astral Projection experience. These are not, directly, issues with the Mod but rather due to how the game works, and the effort to fix them would likely result in incompatibilities and glitches, therefore they have been left as-is.

? Certain NPCs are Scripted to seek-out and interact with the Player. Even when Astral Projecting these NPCs will be aware of the Player and able to locate and speak with them; they will still not be able to visually locate the Player, and will therefore be unable to attack the PC.
? Various background Activators (such as Scene Triggers) still detect the PC whilst they are Astral Projecting, because they PC still physically exists within the game world; this means certain events will still react as though the Player was physically there.
? You are able to drop Items from your Inventory, and change which Items you currently have equipped; however, whilst Astral Projecting you cannot pick-up new Items.

? Astral Shift cannot be aborted
