You don't need make gate or complicated trap for high level. Just make 2-3 large bear trap and put it straight like OOO like this and make sure the trap is between you rex like this (rex)the trap(you). Low level only need 11+ tranq arrow and 3+ scorpion kibble and do not need any narcotic if you use kibble but you can bring it for unexpected thing or not enough kibble. This trap also work on low level spino or other dino. But alway remeber that it only work on low level dino and you can make 4 large bear trap.
