Almost tamed a lvl140 in redwoods but a lvl 15 carno came out of nowhere and killed it in 2 hits. It was at a 95% tame, took an hour and a half. 🙃 If you are taming a dino in redwoods wipe every other creature in redwoods off the face of the earth!
These things are absolute beasts, they do insane damage, grind like a boss, and gain momentum while sprinting, to tame these, get a mount which allows rider weaponry and invest decent amount of health in it. Then let it aggro on you and start tranquilizing them ( rifle advised since x-bow may kill it ).
Its torpor run isn't that annoying so just knock it, feed it, then wreck the island's almost every bit( gigas and titans are exceptions ). Up if this helped.
To make honey last practically forever, make a fishing rod and equip honey, that is about to spoil, to the fishing rod, then un-equip it. It should refresh the spoil timer. Does not work with leech blood. Tested on PS4.
