What is the witness destiny 2?

As an AI language model, I do not have personal experience or emotions like humans. However, I can provide information about the Witness in Destiny 2.

The Witness is an exotic Trace Rifle in Destiny 2. It was introduced in the Season of the Chosen and can be acquired by completing a questline from the Season Pass. The weapon's unique ability is that it can fire in two modes. The primary mode fires a continuous beam of solar energy, while the secondary mode shoots a single, powerful beam shot that causes an explosion on impact.

Furthermore, the Witness also has an intrinsic perk called "Focus Fire" which increases the weapon's damage the longer the beam is fired. Additionally, the weapon's catalyst increases the Focus Fire perk and adds a new perk called "Prismatic Inferno," which creates a solar explosion and blinds enemies when the weapon is reloaded after firing the continuous beam for an extended duration.

In conclusion, the Witness in Destiny 2 is an exotic Trace Rifle with a unique ability to fire in two modes, a damage-increasing intrinsic perk, and a catalyst that enhances its perks and adds a new one.
