Using the Secondary Fire of the Mutalist Quanta and afterwards firing the Nukor through the sphere is an efficient way to utilize the high critical damage multiplier of the Nukor as it adds a flat +60% critical chance (and an additional flat +1.8x critical damage multiplier) after all mods have been calculated.
Enemies affected by Nukor will temporarily take double damage from the Nukor itself and 50% more damage from all succeeding attacks, including other weapons and powers, this effect is listed visually by the increase of size to select bodyparts.
Despite the visual indication of this being for specific body parts, the damage resistance debuff applies regardless of the bodypart targeted.
The damage resistance debuff effect has a limited duration and will be reapplied upon contact and continued use of the Nukor's beam.
This is the first known manufactured Grineer energy weapon and the second gun to deal pure radiation damage, the first being the Detron.
The Seer is technically the first Grineer energy weapon, as its projectiles appear to be energy; as well when reloading the magazine, an energy like substance appears to discharge. Though there is the possibility that these projectiles could be superheated materials.
The Seer is also composed of Orokin technology, and not actually made by the Grineer entirely; this can bring to question whether or not the Grineer possessed the technology and/or know how to create an energy source or if it was simply salvaged from the Orokin tech.
As a microwave beam weapon, the Nukor could be considered a maser - such devices work similar to lasers, but using lower frequency microwave radiation.
The name itself is likely a nod to 'nuking', a term used to refer to cooking/reheating food or drink using a microwave oven.
As the Nukor is being fired, its magazine will rotate and its front encasing will slowly open up. This can be assumed to be a method of cooling the weapon as it heats up during operation.
The aimed body part of the target inflates in size as the target is damaged, as demonstrated by the picture above. This also works on bosses and other Warframes in PvP.
Enemies killed by the Nukor dissolve in a fashion similar to Nova's Molecular Prime, however this effect is purely visual and corpses can still be Desecrated.
If said enemies had been killed by Nukor damage and sliced in half, the corpses will reappear.
Oddly, the Nukor has two separate energy colors when used with its default pallet, being orange for the weapon energy colors themselves and blue for its radioactive beam and warped circles.
This however changes when the user is applying their own energy color and will apply the singular color to both.
Previously, the Nukor's beam was treated as a source of AoE damage (such as an explosion) from point of contact of the Nukor's beam, allowing it to penetrate Shield Lancer's shields (not to be confused with Punch Through).
Enlargement can cause several clipping or graphical issues including parts growing too big as to make them see through in some places, or in extreme cases can make enemies glitch and stretch out into the environment after death.
