Eidolon Teralyst

Teralysts are Sentient creatures found in the Plains of Eidolon at night.

Behavior
Teralysts generally walk in one direction, even if other Tenno are nearby.*

- Upon one of the Teralyst's weak points being destroyed, it will emit a massive explosion after a short delay, then teleport to a random part of the map.

- Teralyst has many attacks (Some abilities missing):
 * Ground Slam: Sends out a shock wave that pushes any warframe or operator in its path back a great distance. Also damages. Jumping will dodge this ability.
 * Ground Smash: Sends a series of explosions to each Tenno's current position. Moving after the ability is cast can successfully prevent the damage.
 * Gun Swing: Teralyst takes its gun (left arm) and swings it in a wide arc. It is suggested that you do not get hit by this.
 * Bullet Rain: Teralyst fires a massive amount of bullets into the air, after which they rain down on all targets nearby. Being in the air seems to avoid the damage outright. It is unknown if being in the Rift via Limbo will prevent the damage.
 * Seeking Bullets: A ball of light is emitted. After a short delay, many projectiles appear and seek out any nearby targets. This attack does not seem to be very accurate, and is easily dodged.

Work in progress.

Strategy
Teralyst has many different attacks, but they are all telegraphed. Once acquainted, players should be able to easily avoid the most damaging attacks, as is required, else your party will die.

- Until shields are removed, Teralyst cannot be damaged. Using the operator's void beam will slowly take out the shields. Dashing in and out of operator mode can help prevent damage during this stage, allowing all members to focus on removing the shield instead of healing others.

- When no shields are present, there are four weak points that can be targeted. It is advisable to only focus on one point at a time.

- Once a weak point is destroyed, the Teralyst will emit a damaging blast and teleport to a different location in the map. At this time, any existing damage to other weak points (needs conformation) is healed. Finding the Teralyst will resume the fight.

Stage 2

-Once two weak points have been destroyed and the Teralyst is at 50% health it will begin two new attack patterns and modify one of the previous. The first new attack patter is it will charge up the arm cannon and proceed to fire directly into the air. A massive AoE will then begin where explosive projectiles rain down from orbit. These detonate upon colliding with the ground so staying airborne can be useful. The second new attack is that the small sentient enemies spawned around the Teralyst will launch exploding spheres similar to the large Aoe but with many fewer projectiles. This is best solved by simply keeping the number of smaller sentients to a minimum which is also important because from 1 point destroyed on the smaller units will help the Teralyst recover shields until they are destroyed, with more sentients leading to faster regeneration. Finally, the AoE fissure stomp where teal blasts pop up will begin to occasionally spread in a starburst pattern rather than merely circling from the front to the back.

(Above is what happens until 50% health, need more information on the final two stages)
