H-09 Efervon Tank

The H-09 Efervon Tank is a and hybrid boss found in Victory Plaza, and an upgraded version of its predecessor, the H-04 Efervon Tank.
One of the strongest weapons of the Scaldra's arsenal, however it appears to be deliberately modified with Techrot enhancements by the tank's engineers, seemingly unbeknownst to Lieutenant Viktor Vodyanoi.
==Behavior==
During the first phase, the H-09 Efervon tank will behave much like a real tank, trying to shoot the players with its main cannon. If a player goes too close, it will do a spin which will knock back the player.
When entering its second phase, it will gain in speed, summoning techrot, and quickly grappling from one end of the fight area to another. When a player gets too close, its tentacles will try to knock the player down.
==Strategy==
===Reaching the Tank===
To reach the H-09 Efervon Tank, players must breach two Scaldra blockades. To do this, they must pick up Emergency Transponders from slain enemies and then hack terminals to summon paratroopers that will drop Thermian RPGs that can destroy the barrier. Each Thermian RPG has 3 shots. The 1st barrier requires 3 shots from a Thermian RPG to destroy, scaled by the amount of players in the squad. The second barrier requires 5 shots from a Thermian RPG to destroy, scaled by the amount of players in the squad.
===Phase 1===
The H-09 Efervon Tank has two health bars. It starts out invulnerable which can be removed by destroying its eight green vents, two above both its treadmills, two above its front, and two above its back.
Once the weakpoints are destroyed, the Tank's invulnerability is removed and it will take damage as normal, but has 85% Damage Reduction. It will summon Scaldra parachuting reinforcements that drop Thermian RPGs. The tank is especially vulnerable to Thermian RPGs, allowing for quicker kills. 
Once the first health bar is depleted, the Tank will regenerate its weakpoints and regain its invincibility. Repeat the process of destroying its weakpoints to remove the invulnerability so you can damage its health. Once it reaches a sliver of a health, an interact prompt to "Destroy Tank" will appear.
===Phase 2===
The floor collapses and Tank suddenly revives itself, revealing spider-like Techrot tendrils. The Tank now possesses health class, is immune to status effects, and summons Techrot enemies in between health bars. The tank is no longer invulnerable, but still possesses 85% damage reduction. Destroying the fleshy green Techrot Proboscis growths on the Tank will deal 5% of its maximum health to the tank, although its new mode of movement via tendrils makes hitting them somewhat more difficult due to its swaying, lifted stance and erratic melee attack patterns.
The Techrot Tank has three health bars. After depleting the first two bars, it will attempt to heal which must be prevented by killing the spawning Techrot enemies.
====H-09 Apex====
There is an optional, but more challenging variant of the boss known as H-09 Apex, which can only be accessed by hacking two green terminals near both blockades on The Steel Path. Upon starting the fight, there are a few special conditions that are activated:
*Fight level will be adjusted depending on how many players are present in the session. This will affect the level of the adds spawned.
**On solo session, enemy level is set to 225.
**On 2-player session, enemy level is set to 250.
**On 3-player session, enemy level is set to 275.
**On a full squad, enemy level is set to 300.
*Much like in Archon Hunts: Self-revives are disabled, Bleedout timer is reduced each time the Tenno has fallen down to a minimum of 5 seconds, 's drain occurs 2 seconds earlier with each use, and the mission will fail upon the death of all players.
*Enemies are replaced by their Eximus counterparts.
*The H-09 Apex can shoot Efervon puddles that nullifies Tenno abilities and inflicts , while healing the Tank. The Scaldra Harbingers assist in spreading the puddles.
Upon its defeat, in addition to its usual drops, the Apex will yield a single and a unique reward: the H-09 Apex Turret Sumdali. If defeated alone with , , , , , and , the player will earn their respective Hex Accolade Glyph.
==Notes==
==Tips==
==Trivia==
*The H-04 and H-09 tanks seem to be primarily based on the T-54/55 series of Soviet MBTs, its distinguishing feature being the gap in between the first and second road wheels (done in real life to balance the tank due to the weight on the rear), alongside the general "bowl" shape of the turret (done in real life for simplified production).
*Viktor's line "We built a machine worthy of the tanks of my father's wars and invulnerable to techrot." upon appearance of the H-09 in its assassination mission, while alluding to the idea that Viktor's father/grandfather fought in WWII (or the Warframe equivalent of such), does have some historical merit, as the hull of the T-54-55 series was based off of the earlier T-44, which entered development as early as 1943.
