Strand is a subclass in Destiny 2 that was introduced in the Lightfall expansion. It is a Darkness subclass that weaves the fabric of reality into deadly abilities. Strand is a movement-focused subclass with access to a grappling hook, crowd control effects, and damage resistance. All Strand subclasses have access to a grappling hook as a grenade ability and multiple ability charges. Titans and Warlocks have three melee charges, and Hunters can access two grenade charges through a certain Aspect. The core gameplay loop of Strand is debuffing your foes and using Tangles to manipulate the battlefield. The easiest way of doing this is by using the subclass new grappling hook grenade, although there are other options for.
However, Strand is not a damage type in Destiny 2. It is a subclass that has its own unique abilities and mechanics, but it does not represent a new damage type. The damage types in Destiny 2 are Arc, Solar, and Void.
