if you are trying to knock out an X-Mosasaur bring at least 3x the tranqs listed, X-Dinos take 3x less damage from you and your tames so as a result they require 3x as many tranqs. I went through 550 tranq arrows and 5.5 crossbows to knockout a 135 and it took 30 mins of non-stop firing so you might want to build a trap. Btw X-dinos also deal 3x as much damage as a non X-dino of the same species I believe so beware!
