Clear / storm the castle and block off the two larger entrances in the middle room which is also the largest, using one behemoth gate and one stone dinosaur gate, then block the 2 staircases with stone foundations and you have an enclosed fort. Finally place some pillars and ceilings in one end of the room to hide underneath of, so you can safely shoot any griffin you trap in the castle room with you?.
i’m a lazy guy, and i don’t usually use traps when i tame things, other than BIG things like a reaper queen or a giga, but THIS IS THE EXCEPTION. unless your dad is apollo, it is impossible to knock one of these guys out without using a trap, for my case anyway. they are ridiculously fast, and they will circle you and attack you. however, the griffin is worth the trouble. it’s one of the fastest fliers, does devastating damage compared to other fliers, other than your typical high-level argy, doesnt need a saddle to ride, can fit two people, and not to mention it looks amazing. however, it can’t pick up many things, it can only pick up smaller creatures. if you carry cryopods around with you though, this shouldn’t be a problem. up this if you found this helpful! -J
A good spot to find them is in crystal isles, by the Wyvern nest. They’re in a little crevice type thingy and they are EVERYWHERE!!!!!! You can just find a good level, lure it into a trap(on YouTube, there is someone named captain fatdog with a ton of good traps!), knock it out, and congratulations, you have a GRIFFIN!!!
