Bungie started adding Exotic Catalysts to Destiny a while ago. Exotic Catalysts basically buffs one of the weapons perks – that could be the weapon’s damage, range, or its actual intrinsic perk. There are only exotic catalysts for Weapons and not Armor pieces.
One of Destiny’s main PvE activity is Nightfall. Nightfalls are just normal strikes with higher difficulty level and exclusive rewards. In Destiny 1, we’ve had some great Nightfall exclusive rewards like Grasp of Malok legendary pulse rifle. As for the PvP i.e, Crucible, Bungie started the pinnacle weapon system for Crucible as well. In Competetive mode, players will get a pinnacle weapon every season after reaching Fabled (2100 Glory rank) and/or completing the weapon’s questline.
