H-09 Apex

: Not to be confused with the similar H-04 Efervon Tank.
H-09 Apex is a and hybrid "super-boss" found in The Steel Path Victory Plaza, and a much more difficult, secret version of the H-09 Efervon Tank.
== Spawning Sequence ==
Spawning the H-09 Apex requires hacking special terminals. These terminals are unmarked and are located by a green glow on the screen, other than the glow they look identical to the regular Stormfall terminals. 
Whilst holding an Emergency Transponder, go to the special terminals. A special version of the coda.worm.nomnom<v1.42> minigame will be initiated, it will be visually purple and text will pop up in the background warning the player to not proceed. By solving this terminal before breaking down the first door, Arthur will say a specific voice line, confirming you've done it right. Another way of determining if you've done it right, beneath the minimap there will be a red Scaldra symbol, and a gray diamond next to it. Then break down the barricade as normal, you can call in more Stormfall units before the barricade is broken if needed. 
Once past the first barricade, repeat the same sequence as before, hack the special terminal before the regular terminal. Once both special terminals are hacked, both symbols underneath the minimap will be red Scaldra symbols, as well as another confirming message from Arthur. Then break down the door and enter the fight as you would normally. 
Ciphers cannot be used to bypass these special terminals, they must be completed manually. Doing so will initiate a High Alert and convince Lieutenant Viktor Vodyanoi to send in an Apex instead of a normal Efervon.

These are based on opinions and may not be 100% true. These should be viewed as advice for finding the enemies until better facts are proven.
==Behavior==
The H-09 Apex retains all of the H-09 Efervon Tank's attacks. Additionally, many of its attacks inflict a unique proc that, alongside distorting their hud and draining their energy, will also dispel active abilities and disable all abilities for 3 seconds. Only buff-based abilities will be disabled (i.e: but not ).
Challenging the H-09 Apex will apply the following modifiers until it is defeated: 
*Self-revive is disabled. A player that dies is permanently out of commission and cannot be brought back. A dead player will be unable to collect the rewards dropped by H-09 Apex, and may also lose their eligibility for any rewards once the 2-minute Inactivity Penalty triggers.
* Last Gasp's drain begins 2 seconds earlier with each use.
*Bleedout timer reduces with each revive, down to a minimum of 5 seconds.
*Team Bonus Consumables have a 3 minute cooldown.
*Deployable allied units such as Specters and On Call Crew cannot be used inside of the arena
**Allies summoned before entering the arena will remain active and follow you into the fight.
**Air Support Charges that summon allies, like the Sentry Gun or Kahl Beacon, can still be used.
*The fight level of enemies spawned by the Apex will scale based upon the size of the current session:
**In solo session, enemy level is set to 225.
**In 2-player session, enemy level is set to 250.
**In 3-player session, enemy level is set to 275.
**In a full squad, enemy level is set to 300.
*All enemies spawned are upgraded to Eximus units whenever possible.
=== Phase 1 ===
During this phase, endless waves of Scaldra Harbingers will spawn outside of the arena, sniping the Tenno. Damage from Efervon sources will apply a Magnetic proc, disable your abilities and dispel active buffs.
Attack 	Description 	How to Counter 	Dispels, Disables and Magnetic
Tank Swipe 	Spins its gun barrel around, staggering and knocking back any Tenno in range. 	Stay outside of the H-09 Apex's melee range. 	✗
Tank Shot 	The H-09 charges an Efervon projectile that inflicts Stagger on hit. 	Watch the H-09's barrel, and dodge when it's about to fire. 	✓
Efervon Flood 	The H-09 aligns its barrel with its front, rear or side, then fires a sweeping beam of Efervon towards the Tenno. This attack covers a quarter of the arena in Efervon. 	Prepare to dodge this attack once the H-09 straightens its barrel. Either move to a safe part of the arena, or use a combination of wallrunning and aimgliding to remain airborne until the Efervon subsides. 	✓
Efervon Mortar 	The tank launches a barrage of Efervon grenades. Terrain struck by this attack is coated in Efervon. If the Tenno isn't in range, the H-09 will instead use its mortar on unblighted ground.	The H-09 will passively use this attack during its first phase, and it can be easily dodged. However, be mindful of the terrain that you lose from this attack. 	✓
Summon Efervon Harbingers	The H-09 Apex deploys unique Scaldra Harbinger balloons that release a stream of Efervon as they fly. They deal Gas damage to players that pass underneath with a chance to inflict status. 	Unlike normal Harbingers, damage dealt to Efervon Harbingers is not increased a critical tier. Either bring a weapon that specializes in non-critical damage such as the Laetum and Phenmor, or clear the H-09 Apex's first phase before they overwhelm you. 	✓
Summon Stormfall 	Eximus Stormfall units are airdropped into the arena. At least two units will wield a Thermian RPG 	Stormfall units will only deploy while the H-09 is vulnerable to damage. Shooting Stormfall's balloons as soon as they deploy will cause them to plummet to their deaths. As this only summons Eximus units, consider using a pistol with Secondary Fortify to steal their Overguard.	✗
==== Phase 2 ====
Unlike the first phase, most of the H-09 Apex's attacks do not disable your abilities or apply a Magnetic proc. You can freely use your operator to dodge most of the tank's attacks.
Attack 	Description 	How to Counter 	Dispels, Disables and Magnetic
Mosh Pit 	The H-09 stomps its feet 1-5 times, each stomp releasing a wave that knocks down Warframes. 	Remain airborne, or time your jumps with the Apex's stomps. As the H-09 remains mostly stationary during this attack, it's an opportune time to pop its cysts. 	✗
Bottle Off 	The Apex swipes one of its side arms, flinging unguided Techrot projectiles across the arena. 	When the Apex uses this attack, quickly dodge to its opposite side. 	✗
Hot Shot 	This attack in mechanically unchanged from the first phase's Tank Shot, but now deals Viral damage. 	As before, watch the H-09's barrel and dodge when it's about to fire. 	✗
Crowdsurf 	The tank flings itself across the arena, then sheds a cluster of Techrot Miasmites. Tenno tackled by the Apex's charge are knocked down. 	Dodge the H-09's initial charge by rolling to the side. Use AoE/CC weapons and abilities to quickly dispatch the Miasmites. It is not advised to ignore the Miasmites, as their guaranteed Stagger on hit can leave you vulnerable to the Apex's other attacks. 	✗
Pyrotechnics 	The Apex unleashes a combination of targeted mortar fire and homing missiles in all directions. 	This attack can be consistently dodged using your Operator. Alternatively, withdraw from the Apex, dodge the initial mortar fire, then jump and roll through the missiles. 	✗
Benefit Gig 	The H-09 becomes immune to damage and screams at the sky, summoning Techrot Eximus throughout the arena. The Techrot will attempt to reach the tank, sacrificing themselves and healing the Apex if they succeed. 	The Apex uses this attack twice; once when its first health bar is initially drained, and again when its second health bar is initially drained. Do your best to prevent the Techrot from reaching the tank, as this can extend the fight and increase the risk of Cascading Fragmentation reaching fatal levels.	✗
Summon Mucuspires 	The Apex digs its front lets into the ground, summoning 2 Techrot Mucuspires elsewhere in the arena. These spires emit infested spores that disable abilities, dispel buffs, and apply a Magnetic proc. They also fire homing missiles with an identical effect on hit. This attack is not used until after the first Benefit Gig. Following the second Gig, this attack will spawn a third Mucuspire.	Destroy the Mucuspires as soon as possible. Like the Efervon Harbingers in the first phase, weapons that specialize in non-critical damage can quickly dispatch these towers. 	✓
Cascading Fragmentation	A soft-enrage sequence that begins at the second phase. Applies all players with a unique debuff known as Cascading Fragmentation, which deals periodic damage and speeds up boss movement. Every 60 seconds the debuff will continuously increase by one stack until the Tenno or the boss is slain. 	Simply defeat the H-09 Apex before the Cascading Fragmentation kills you. 	✗

==Tips==
The H-09 Apex's attacks are mostly limited to Gas, Blast and Viral damage, making Adaptation one of the best mods to counter it. It's also recommended to enhance your airborne abilities with mods like .
