Avatar State

"' The Avatar State is a defence mechanism, designed to empower you with the skills and knowledge of all the past Avatars. The glow is the combination of all your past lives, focusing their energy through your body. In the Avatar State, you are at your most powerful, but you are also at your most vulnerable. If you are killed in the Avatar State, the reincarnation cycle will be broken and the Avatar will cease to exist.'""— Roku to Aang, 99AG"

Activation
The Avatar State can be activated one of two ways: reflexively or masterfully.

Reflexively
This activates when the Avatar is in mortal peril or is emotionally compromised, and puts survival over elegant, well thought-out fighting. It appears that the Avatar does not remember the events of when they are in the state. The state stops when the Avatar is safe, or pacified.

Masterfully
This can be activated by the Avatar out of choice, and as such allows the Avatar to choose what to do with their power.

Effects

 * All modifiers become +5;
 * Your health doubles;
 * Your AC gains +1;
 * You have maximum initiative;
 * You break out of any condition currently upon you (except poison, and physical injury);
 * Your eyes, and tattoos glow bright blue;
 * Your voice becomes distorted and deeper, and;
 * You gain access to the abilities below.

Ice fissure
Avatars are able to use waterbending to split frozen ground by bending the water mixed with the earth.

Remote waterbending
Avatars can use waterbending from distances which a waterbender would not normally be able to access.

Tsunami
Since they can control larger amounts of water, Avatars are capable of creating and controlling water bodies of far greater size and scale, including causing massive tsunamis, at will.

Water compression
An Avatar in the Avatar State has enough power over water to compress its volume, compacting several thousands of gallons into a small volume.

Compressed rock bullets
Aang disintegrated one of his compressed rocks from his Elemental Sphere and shot its shrapnel-like fragments with great speed, in a machine gun-like fashion. Due to the speed and density of these rocks, they did great damage to the landscape. It is similar to the rock gloves technique used by the Dai Li.

Enhanced earth armor
By harnessing the power of the Avatar State, Avatars can surround themselves with large pieces of earth which they can subsequently conglomerate into a giant anthropomorphic rock body to use in combat.

Enhanced earth levitation
With their greater power and stronger connection to the earth, the Avatar can move hill-sized statues at will.

Powered compression
This is a much more powerful version of the earth compression technique, performed only by Aang while in the Avatar State. Instead of bending large chunks of earth into a single projectile, Aang gathered boulder-sized rocks and simultaneously compressed each fragment into smaller, denser, and harder rocks, essentially keeping the rocks under pressure for more volatile attacks if needed. Lastly, the rocks are directed to orbit the bender until they are used.

Tectonics
The Avatar can earthbend on a scale vast enough to move entire landmasses.

Long-range multiple fire whips
An Avatar-level firebender can produce fire whips, the most being five at once. They are capable of reaching across long distances. They have enough destructive power to demolish large rock formations.

Air sphere
With this technique, the Avatar creates a sphere of air around them, allowing them to hover for extended periods of time or fly at high speeds. The sphere also acts as a barrier to protect the Avatar, strong enough to withstand a high velocity impact with rock.

Strong winds
It is possible for the Avatar to unleash extremely powerful winds.

Tornadoes/hurricanes
In addition to large and powerful air movements, an Avatar level airbender can create massive tornadoes and hurricanes at will.
