Best method I was told. Build a 2x2 stone [or wood if low] foundation with 2 high walls, drop in with flyer, feed through wall. Has a massive hitbox to feed it through if lured close to a wall. No repel needed with this method.
Valguero Taming Guide: Mantises spawn at the bottom of the Wyvern Scar. To tame them, first you will need to go to Scorched Earth and wall around the North, West, and South deserts at the perimeter of the map. Each circuit around the map should give you 5-10 horns. Horns can be collected from Iceworms in Ragnarok as well.
Once you have your horns, equip a full ghillie suit and bug repellant. Approach the scar from the East, and you should see two cliff platforms in the snow at the entrance to the Scar. There will almost always be several Mantises on the ramp descending into the scar along with dung beetles, titanaboas, and arthros.
Clear the trash, agro a mantis, and run back up the ramp and onto the snow platforms. Mantis should lose agro on the platforms, and you can then start taming peacefully. Approach from behind with your ghillie suit and bug repllant, passive tame with the horns and feed every 3 minutes. Voila, easy Mantis. I tamed 4 in less than 2 hours like this.
The most versatile of Scorched Earths creatures. A Mantis can hold the roles of multiple different creatures depending on the tools or weapons it has equipped. Picks and Hatchets make them ultimate harvesters, Pikes and Swords can turn them into deadly combat mounts and Clubs can allow them to quickly down creatures for taming, they have no need for Sickles since they can harvest fiber by default. However you'll need to level it's stats depending on the role you plan to assign it to. For example, if you want too make a Mantis a harvester weight and Melee are what you'll want to go for, if you want it to be a expert at combat health and Melee with some stamina in case things go wrong and you have to flee are the way to go since there pounce attack is enough to quickly cover ground and escape a aggressor, and KO'ers really need nothing more then health in case the target is something strong that fights back and some Melee to increase the amount of torpor inflicted by the clubs
Best way to farm an element vein. Get an Ascendant Pickaxe and swing away. Do the outer ones first. Level only melee. Weight doesnt matter because in the end you want more element and can just carry it on your flyer.
So these are a passive tame, get some bug repellent ( make it ok a mortar or a chem bench and you’ll need; narc, lemons, carrots and pelt)
You will also need Deathworm horns for the actual taming, put them in the last slot on the quick access bar.
Find the Mantis that you want, use the bug repellent (you’ll get about 400 seconds) and no insects will agro by you being near them. Approach the mantis from behind and feed them to it.
It may takes more than one feed? If that’s the case be aware that the mantis will agro for a bit.
