Lephantis

Lephantis is a massive, multi-headed Infested boss created to fight in the Old War, introduced in . This large amalgamated creature consists of three heads called Infested Corpus, Infested Grineer, and Ancient Infested, which can seemingly extend and are attached to a tripod-like body hidden beneath the ground.
It is found on Magnacidium, Deimos. After defeating it and finishing the mission, the player will receive a component blueprint. Each of its heads are also capable of dropping Neurodes and Orokin Cells in addition to its main body, potentially totaling up to four resource drops.
==Behavior==
Throughout Phase 1, each of Lephantis' three heads will emerge from the ground before attacking, which causes knockdown to any nearby Tenno. In Phase 2, its main body can create shockwaves that knockdown.
<tabber>|-|Infested Corpus=
The Infested Corpus head resembles a severely mutated Corpus helmet with a mouth taking up its entire face, with a set of tentacles on either side that cover it up when not attacking. It can spit deadly poison grenades at great distances, leaving behind clouds that deal high damage and ignore shields. It can also release Infested spawn pods similar to those dropped by Boilers which will spawn multiple basic Infested units over time until it is either destroyed or expires on its own, leaving behind a cloud of poison.
|-|Infested Grineer=
The Infested Grineer head has a three-pronged jaw and wields a massive organic scythe-arm. It will either swing its scythe in a wide horizontal sweep or downward with an overhead strike. The scythe is capable of destroying obstacles in the arena as well as inflicting knockdowns with every hit. Its face is located below the jaw, which appears to be the Grineer that was merged into Lephantis long ago; it will only reveal itself when it attacks.
|-|Ancient Infested=
The Ancient Infested head sports a long, stout jaw as well as the "crown" that normal Ancients have on their backs. It will spit an arc of Spore Bombs that explode a second after hitting the ground. While the bombs have a wide radius and deal a high amount of damage, they do not ignore shields.

==Damage Reduction==
During phase 1, each of Lephantis's heads possesses an innate 60% DR.
During phase 2, this is increased to 70% DR.
Lephantis also possesses Damage Reduction that scales depending on your weapon's damage. Damage is calculated by
:\text{Modded Damage} \times \text{Critical Multiplier (if triggered)} \times \text{Body Part Multipliers} \times \text{Innate DR}
Additionally, the damage is calculated using all health damage type modifiers, and is quantized.
Critical hits have their damage doubled on top of the weapon's critical multiplier.
{
\text{Damage Multiplier} =
\begin{cases}
1,\; & \text{Damage} \leq 450 \\
0.1 + \frac{450}{\text{Damage}},\; & 450 < \text{Damage}
\end{cases}
}
If a head is hit again within approximately 0.27 seconds, whether from multishot or simply firing again, the hit uses the following modifier instead:
\text{Damage Multiplier} = 0.1
In addition, during Phase 2, each head possesses a damage cap. The cap is calculated for each damage instance, not the sum of hits.
\text{Damage Cap} = 0.1 \times \text{Current Head Health} + 450
In summary, bringing weapons with low damage but high fire rate such as fully automatic rifles are far more effective than weapons that deals high damage in a single shot such as snipers.
==Strategy==
===Phase 1===
Throughout the fight, each of Lephantis's heads will emerge from the ground in intervals and attack, allowing players to hit them. They are all completely immune to damage except on their pink weak spots, which are only revealed when they attack: the Corpus head's weak spot is its mouth, the Ancient head's weak spot is its neck, and the Grineer head has two weak spots - the mouth and the "face", with the latter taking 2x damage.
The fight begins with the Infested Corpus head appearing first, and the Ancient Infested head following soon after. When enough combined damage has been dealt to the Corpus and Ancient heads, they will temporarily retreat and the Grineer head will emerge alone. After the Grineer head retreats, all three heads will be able to emerge and attack together.
===Phase 2===
Once all three heads have been defeated, the ground will rumble and all three heads will emerge at once, destroying the entire floor. Players will fall down into the ruins below, where the body of Lephantis resides. This area is darker and has small pools of electrified water, which cause players to take damage when stepping in them.
Phase 2 is much the same as Phase 1, except all three heads are present at the same time and they cannot retreat, attached to its main body which stomps around and rotates in its arena. Once a head is defeated, it will explode and leave behind a stump on Lephantis' body that will periodically spit out Spore Grenades.
Once all heads have been destroyed, the body of Lephantis will collapse and explode.
===Summary===
*Phase 1: Wait for Lephantis's heads to emerge and reveal their weakspot, then deplete their health.
*Phase 2: All of Lephantis's heads are now permanently active. Repeat above once more.
==Notes==
* can be damaged by the Corpus and Infested heads' projectile attacks while in the Rift plane, so it is advisable to keep moving while in the Rift.
* cannot use her Peacemaker ability to damage the heads, as the ability targets the center mass of the body, rather than the damageable weak points.
*The Lephantis fight may be made easier through a combination of slowing abilities that extend the window to attack its weak spots for longer 
** Using the aura will slow all Infested ーincluding Lephantisー by up to 18% at max rank. 
** Warframe abilities such as 's , 's , 's , and 's . 's will also slow Lephantis in addition to providing energy. 
** With the Zenurik focus schools' the Lephantis will be slowed up to 80% for 10 seconds at max rank.
* can use to stay airborne and easily avoid most of Lephantis' attacks while dealing high damage.
**Targeting the heads however might become difficult, as Lephantis will re-position itself and seek after Titania's razorflies instead of Titania herself.
* can potentially, although rarely, highlight a weak spot with , allowing for increased damage to it.
* can use 's Gaze to "freeze" the first phase heads weak spots to easily dish out enough damage to one-shot it after the ability expires.
*Players can scan the individual heads in the first phase and scan Lephantis' body in the second phase. However, only the body scan counts towards the Codex entry.
*Using weapons that have innate punch through or using punch through mods can allow the user to shoot through invulnerable parts of Lephantis to hit the weak spots. This is only possible when weak spots are already revealed, as the heads otherwise have stages of total invulnerability.
*Using a Specter and having it hold position can be useful to keep Lephantis from rotating or moving around, although the specter will despawn after phase transition.
*If the player has attracted and spawned a Juggernaut, it is recommended to kill it before starting Lephantis' fight, as the Juggernaut will follow the player into the fight otherwise. This may make the fight significantly harder as Juggernaut's gas cloud attack affects a large area, which may be dangerous in the close quarters of the fight, and it can also spawn additional Infested enemies.
*If tackling solo, with one or more specters, be aware that this mission will auto-fail if the player does not kill an enemy within 15 minutes (heads do not count, specter kills do not count).
*Lephantis' heads in its first phase are affected by, and not unsusceptible to, the Nightmare Death Detonation mode modifier, and will "explode" upon being killed. This will result in the encounter becoming softlocked, as the heads cannot perform the animation of being pulled back under the floor, and further heads will simply not spawn.
==Trivia==
*Lephantis was previously known as the J-2000 Golem. It was originally going to replace the now retired J3-Golem boss on Jupiter, but was moved to the Orokin Derelict tileset instead.
*Lephantis was the first boss to not directly drop a blueprint. Players would always get a blueprint for one of 's components as a mission reward once they reach extraction. Later updates have since applied this to the other bosses.
*Underneath the Infested Grineer head there is a person's face, akin to Dark Sector boss Mezner who also is fought in a large arena-type area and whose face is distorted and stretched over the Infested creature.
*Lephantis' taunt sounds are similar to those of Lieutenant Lech Kril, albeit more distorted.
*Originally upon defeating the three heads in Phase 1, the ceiling would break causing the floor to crumble from the falling debris. This was changed in favor of Lephantis breaking the ground directly.
*Lephantis is currently the second-largest Assassination boss in the game, beaten only by the Jordas Golem.
**Coincidentally, both are Infested bosses.
*A hologram of Lephantis can be seen in the Dojo Bio Labs. Furthermore, to the left of the hologram one of Lephantis' legs is enclosed within one of the containers.
*Each head of Lephantis may be a reference to The Three Wise Monkeys, with the Infested Ancient head covering the sides (which could represent ears), the Infested Grineer head covering an eye-like stalk, and the Infested Corpus head covering its mouth.
*Lephantis' line "Why do you destroy us? We are your flesh" heavily alluded to Warframes being Infested. This was in the game for 5 years before it was confirmed to be true in The Sacrifice.
