One huge plus for Ophidian aspect would be a better melee range for the stasis melee ability because the range now as it is is to close to reach enemies far away but to close to be triggered by enemies close to me.

Is the Ophidian Aspect good?

Enter the Ophidian Aspects. Ophidians add plus 30 to Handling and Reload speed, while increasing the range of your melee. The reload speed and melee range buffs are certainly noticeable and useful, but the real argument for using them is the buff to the Handling stat of your weapons.

How do you get the Ophidian aspect in Destiny 2?

The simplest way is to obtain it from an exotic engram drop. It's a random roll, so you'll have to get lucky, and you might find the pair you're looking to build around your Guardian. The second way you can get it is by looting it through the Luminous Engram, which you acquire from the weekly Milestones.
