Taking this sauropod is no joke, but here are some tips to help you out:
1. Knockout taming is a little easier, and faster, however, it requires much more food, and in passive taming, the effectiveness is higher, either is ok, so choose one that works for you, I just prefer passive taming it
2. I highly recommend a trap, knocking it out would be difficult without, and could kill you, if it knocks you off a cliff. In passive, any time it is hit by a wild creature, it resets the taming bar, so a trap is essential, especially the higher level it is.
3. Honestly Mejos work great, but are a lot slower, yet easier to get than kibble. Effectiveness is near perfect with them so don’t worry.
4. If passive taming, you can stand slightly farther back than its back legs, and it will try to hit you and be unable, so it will keep trying to hit, and you can stand there forever, feeding it
5. After the first feed (in passive taming), it needs to wait around 15 to 25 minutes (in my experience) before it eats again. Then it is around 20 seconds, unless its hunger is full, in which case it will let you feed it again when it goes down enough for whatever food you are using.
Know that it is easiest to passive tame them, which means walking up to them and feeding them
Get a TON of berries, everytime you feed it, it will go up like 3-5%
Have a high speed, high attack flying dino, (high attack in case you "miss click")
HAVE PATIENCE, diplo's are a stubborn tame, they will push you playfully (hence the flying dino)
MAKE SURE there are no carnivores around, if there are carnies around it will attack it there is a chance of it dying, it will get rid of all your hard work, and most importantly, IT MAY DIE (R.I.P. attempted tame #1 + 2 😢)
Plz note I am not an "high level player" that has a giga, I am lvl 50, (51 at the time I wrote this, almost 52) so I am not that experienced, tho I am sorta, I don't know that much about the game
Very easy tame! Just go by a rock while getting hit, so you don’t go far away, and go under the diplo. Keep feeding it mejoberries, and wala you have a diplo. Keep in mind the little bonks don’t hurt so don’t be afraid by that.
Passive tamed a level 12 (+5 levels) with 15 mejoberries. If you can situate yourself under it’s legs, specifically between the two front ones, the diplo will continue to try and bump you back but will be unsuccessful. It will do this move over and over again, and drain its stamina and hunger faster, which leads to a faster tame.
