I go to center caves, 2 in redwoods and floating island are best. Full ghillie, bug repellant, sacrificial sheep, chainsaw, sleeping bags, preserving salt. Use wyvern wing flap your target to safe area make sure bat is just above character level. Kill that ovis with chainsaw! Place sleeping bag just in case.. Put taming mutton in inventory with half stack of salt. Rest of salt and mutton into wyvern. Ghillie up! Bug spray! Walk slow! Stand under feed, do not move. Stand there for 5 mins(might be shorter but dang its long) it goes faster after that first bite. Keep track of repellent back away slow and reapply if needed! Perfect tame every time!

I WANT TO MAKE CLEAR THIS IS A PASIVE TAME THERE FOR YOU MUST SHOVE FOOD UP ITS BUT WITHOUT IT NOTICING YOU AKA TRAP IT AND USE BUG REPL AND GILLY GEAR THEN SHOVE THE BEST (MEAT) ON IT

This is a great guard tame get at least 5 or 6 and have them placed inside of a house and if someone breaks in they will kill the enemies very fast and very effectively

Bug repellant is not a necessity, it can be replaced by crawling and using a ghillie suit. This works on all passive cave tames.

Mainly used in PvP to destroy player's armor, the Onyc is a guard animal. To maximize efectiveness upgrade health, damage, and speed.

Nah nah nah nah nah nah nah nah batman!!!!!

Two words:
Flame Thrower

Probably the easiest way to tame theses guys is to make a 1 foundation hut, draw him to it, get him stuck by placing down your last wall, walk away until you lose agro, then use bug repellent

Trap it, shove meat up it's butt without it noticing, yet not really sure, how do they not feel something going up their bumholes? Anyway that's off topic and then you have a tamed rabie monster.

It's a slower, but more accurate and powerful version of the Dimorph. It can't carry a lot, move fast or take down larger creatures. but a good distraction/sacrificial lamb or decorative pet.

You can absolutely tame them through a wall still. Just finished a 145 tame with mutton, because kibble does not work. Build a 3x1 hallway with no walls on either end, agro run through place a wall in front of it, run around and wall it off. Barely derender, feed through the wall. 21 mutton for a 150, 4.5% per feed. ♡Hz

Some caves are untamable bats, while others are fine, wiki page has a map

If trying to tame on center be careful cause it may fly up into the skybox right when it is tamed.
Source: Happened to me.

the upper south cave, the north east cave, the caverns of lost hope, the caverns of lost faith and the tek cave are not on mobile, and they don't spawn at the swamp cave or snow cave. i found them in the north west cave, and besides the terrifying cliffs, it was pretty ok. just take some bug repellent and warm armor. and they just sit in certain spots in clusters. the only other creatures in there are araneos, so with a few bug repellents, it's actually pretty easy, but without them the clusters of bats and spiders can be dangerous. you can avoid the cliffs if you don't care about the artifact, but unfortunately if you do want that, you'll have to brave at least one cliff. the cave entrance is so small that i couldn't get my onyc out, so i had to request it.

Unfortunately you she to tame these to get the Dino tamer achievement. After taking one, I just say suck it up and miss the achievement.

Lots of them at the jungle castle in ragnarok, but most of them are too high level to tame; I found a level around 450 there

They can't be tamed on genesis for now some how when you try to feed him nothing happen

Lure them out the cave to make the taming process 10x easier. :)

Watch out when taming, these dudes can carry rabies

A wonderful"guard dog" even for late game players. A few of these inside your house and anyone who tries to raid you will show up dead in your tribe manager quite a bit. These little suckers are about as overpowered in close quarters combat as it comes.
