Be ready for a long tame if you don't have titanboa kibble and you're looking for a high level! Bf and I tamed two level 8's with prime meat and it took over a half hour for each with taming speed at x3. Torpor drops pretty fast too. Can take down fairly quick with crossbow tho. Totally worth taming these guys 'cause running up walls and cliffs is fun as heck! :D
The redwoods are now basically a no fly zone, I lost a quetz, and a pter to these bastards. They jump out of the tree, rip you off your mount, and then pin you and your mastercraft armor to the ground and murder you.
Easiest way to tame: make a dino pen, pick one up with an argy, put it in the dino pen then follow along with a basic taming process (knock it out, feed it). Make sure you have lots of narcotics on you!
Best thing about them: they can climb up really steep hills and they can potentially do lots of damage and can be fast.
Where to find: most commonly found on trees (they will be hanging upside down, high up on large trees) in the redwood forest areas (mainly on The Center) or I find lots of them in the Ragnorok desert.
