Onos

Orokin Weapons

Onos is an  Entrati wrist-mounted cannon turned into an Incarnon weapon by Albrecht Entrati. Normally capable of shooting fully automatic  Puncture projectiles, its Incarnon Form transforms into a charging Arm Cannon that primes a  Radiation wave to discharge  Heat lasers.

Characteristics[]

• This weapon deals pure  Puncture damage in its normal form and primarily  Heat damage in its Incarnon Form.
• Once Incarnon Form is unlocked, landing headshots fill the Incarnon Transmutation gauge that transforms the Onos into a charging Arm Cannon via the Alternate Fire key.
  • The gauge reaches full charge after 12 headshots, and does not require a full gauge to activate. It will also emit a small, ghost-like wail when the gauge is completely full.
    • Additional shots from Multishot count as separate headshots.
  • While charging, the cannon releases a wide beam that inflicts  Radiation damage that narrows the longer the charge is held. Upon a full charge, it releases a beam that deals  Heat damage and status with 5 meter Punch Through and explodes in a 3 meter radius.
    • Initial hit and explosion apply status separately.
    • Explosion does not need direct line of sight to deal damage and will penetrate walls.
  • Instead of drawing from the Onos's ammo reserves, Incarnon Form gives the Onos a unique "magazine" from 30 rounds per charge to a maximum of 350, indicated by the regular ammo HUD and a bar underneath the reticle.
    • If the Alternate Fire key is pressed whether or not the Incarnon magazine is fully expended, the Onos is transformed back into its default state, however this will also fully expend any remaining Incarnon gauge.
• As an Incarnon weapon, Onos has 5 evolution tiers with different perks that allow players to customize their Onos's stats.

Notes[]

•  Yareli is unable to activate nor use the Onos' Incarnon Form if she is mounted on  Merulina.
  • Attempting to activate the Onos' Incarnon Form while dismounted, then mounting Merulina immediately afterwards, will force the Onos to revert back to its default form.
    • This causes a bug with Onos' firing SFX, it will not play.
    • The weapon mode indicator at the bottom right will display that the weapon is in Incarnon Form, but this is a bug, as the Onos is actually in its default form.
    • Forcing the Onos to revert to its default form in this manner will not consume any Incarnon charges. Dismounting Merulina will then allow you to immediately activate Onos' Incarnon Form using the unused charges (and any charge you gained firing the Onos in its default form while mounted on Merulina, up to the Onos' Incarnon charge cap).
      • It is not known if this specific interaction is intended, or a bug.
  • This conflict does not apply if using  Loyal Merulina.

Evolutions[]

• When newly acquired from the Foundry, players must acquire 100 kills with the Onos in order to gain access to its Incarnon transformation. The following Evolution tiers, their requirements for unlocking them, and their related perks, are shown below;
  • Each challenge additionally grants 5,000 affinity to the weapon, affected by Affinity Boosters.

Evolution I[]

• Unlock Challenge: Kill 100 enemies with the Onos.
• Headshots charge Incarnon Transmutation; Alt Fire transmutes. Switching back will expend any remaining charge.
  • Incarnon Form changes the weapon from an automatic hand cannon to charging Arm-Cannon. Holding down the trigger releases a wide beam that inflicts  Radiation damage. The beam narrows and increases in damage the longer the charge is held. Once fully charged, the Arm Cannon releases a powerful  Heat shot with guaranteed status, 5 meter Punch Through, and explodes in a 3 meter radius.
    • Damage scales linearly up to 3x damage. Resets after releasing the trigger or firing a charged shot.
  • Incarnon Form uses Arm-Cannon animations. Contrary to its appearance, the Onos is still considered a Secondary weapon.
• Mode switching is not instantaneous and has an animation equal to the weapon's reload speed.
• Incarnon Form is activated by filling the Incarnon Transmutation gauge that appears under the reticule by achieving headshots and then pressing the Alternate Fire button. 12 headshots will completely fill the gauge. A full gauge is not required to activate Incarnon Form.
  • Charges generate only on headshots, and not other weakspots, such as the backpacks of most MOA variants. Similarly, shooting weakspots generated by either  Sonar or  Detect Vulnerability in places other than heads will have no effect either.
  • Headshots on corpses do not build charges.
  • Headshots must do damage to the enemy to build charges. invulnerable targets such as Well of Life and Lantern targets do not build charges.
  • Individual Multishot bullets can build charges.
• Instead of drawing ammunition from its reserves, the Onos's Incarnon Form uses a separate "magazine" with each charge producing 30 rounds to a maximum of 350. Once all ammunition is expended, the Onos reverts to its normal form.
  • Onos consumes 1 round per tick of damage, then 50 rounds upon releasing the  Heat beam. the charged beam will deal full damage even if there's less than 50 charges remaining.
  • Incarnon Form's magazine is not affected by mods.
  • Incarnon Form is not affected by Ammo Efficiency (such as  Energized Munitions).
  • Charges and Incarnon Form persists through all activities, such as holstering, bleedout, or being disarmed. However, charges and Incarnon Form are removed upon death.
