Originally, there were four elemental Drakes; the Mountain, Ocean, Infernal, and Cloud ones. Then, Riot Games added two more; Hextech and Chemtech Drakes. While the Hextech Drake was successful, the Chemtech Drake had several problems; the buffs weren't good for the players, and they also had a lot of bugs and problems caused by the Chemtech Drake's dominance, which created zones in the Rift that makes Champions get camouflage.  The players protested against this Dragon, and in January 2022, it got eliminated from the game. Riot said it is getting reworked, but some time has passed, and this Drake is still out of the game.
