Vex: Solar and Void, mainly solar (Line rifle and Slap rifle; Solar, Torch hammer and Cyclops for void) Cabal; Solar and Arc (dunno the weapons) Taken: All 3. Skorn: All 3. Depends on the individual enemies within the faction. Fallen are mostly Arc, except captains and some dregs/vandals with Shrapnel Cannons which are solar. Vex are kind of a mix.

This guide covers every enemy type in Destiny 2, including their combatant type, elemental shields, and more. This will help you better choose your weapons and armor mods when tackling endgame content.

For example: vex hobgoblins shoot red solar shots, vex wyverns shoot purple void shots, and vex fanatics explode dealing light blue arc damage. Look at what color their projectile is (or associated audio cues for melee weapons) and it should be relatively easy to deduce.

There are six damage types: Kinetic: White — the default damage type on most weapons, causes generic damage to any enemy. Solar: Orange — causes Solar damage. Arc: Blue — causes Arc damage. Void: Purple — causes Void damage. Stasis: Indigo — causes Stasis damage. Strand: Green — causes Strand damage.
