While it is charging, the Opticor emits a beam of light that is colored the same as its energy color. This targeting beam follows parallel to the path of the projectile, and other players can see it. The fired projectile will not follow the path of the beam.
When a fully charged shot is fired, the shot leaves a particle effect in its wake consisting of striations of energy the same color as the gun's energy color. These are visually appealing but also may obscure vision of the target.
Whilst starting out, make use of the Opticor's starting x20px slot to fit Shred or Serration to enhance its AoE potential, and/or damage output. Heavy Caliber's accuracy drop is also very marginal, making it another good choice.
Said polarity slot is all the way at the bottom right slot, meaning that if used in Solar Rail Conflicts, the mod in this slot will be the very last one to be acquired. This can be rectified with the use of a Forma to change the polarized slot's position.
A critical chance increase and/or critical damage increase can offer immense damage when getting a critical. Even simply increasing the critical chance to 37.5% with Split Chamber and Point Strike is sufficient.
Works well in combination with Nova's Antimatter Drop due to the weapon's pin-point accuracy and massive damage, allowing Antimatter Drop to deal large amounts of damage with only a single shot.
Shred is recommended for this weapon as it improves the charge time while adding Punch Through. This makes the Opticor much more effective in narrow hallways.
The Opticor treats the Shield Lancer's shield as a solid environmental surface, setting off its AoE damage effect. Shooting at Shield Lancers in the midst of enemy Grineer can be a good alternative to shooting the ground to deal splash damage.
At the time of its introduction, firing the weapon at 50% yielded the same damage as firing at full charge, meaning charging the weapon past 50% served no purpose other than to afford additional time to aim. This was fixed in Update 15.0.7.
There are slight visual differences between partially-charged shots and fully-charged shots; fully-charged shots are wider and leave a short-lived trail of light after the main shot has dissipated.
