Pretty standard knock out tame. But you definitely need a trap and distance to avoid the fire breath and stomps as well as keep it from running into lava. Which it could survive

Trapping it with doorframes helps, try to use shocking tranqs with headshots. Sit on a Pyromane whilst shooting to avoid all flamethrower damage.

It's a standard knockout, yet you should be aware that higher levels are very strong.

I recommend to either bring a Pyromane or the best idea is to build a trap and lure it into the trap. As soon as Boaratos start firing, just get out of his fire attack radius and snipe it with darts from a distance.

Boaratos can easily kill you with its flame attack, so anything to extinguish yourself or avoid fire damage, is a good idea.

Very basic 3x3 1 height stone enclosure trap is enough to tame. Based on your server settings, bring a lot of narcotics as it seems torpor goes really quickly down, like Giga's does. If you let it attack multiple times before putting it into sleep, you can deplete a lot of his hunger and tame it quicker.

It's also a good idea to kill any nearby Boaratos you don't want to tame, as they are very aggressive and have really huge AoE range for fiery attack. It drops Beacon after killing it and it's being spawned on Therokis (the centered lava island on Astraeos map).

Use metal billboards, shocking darts, best longneck you have and bring narcs to keep out wakes up fast.

If you put it in a trap in shallow water it won't be able to damage Stone or set you on fire

For taming this id say make sure its in a trap and id say for the gigantic torpor use the lost colony bow if u have it, i used it to tame a 130 boaratos knocked unconscious after a few mins but only problem is the bow deals a lot of health damage too

He can break through all kinds of trap so be careful

Takes about 60 shocking tranq darts with a 220% rifle, torpor drains SUPER fast, but eats fast too

EASIEST TAMING OFFICIAL PVE:

4 metal foundations and 8 metal walls (double door frame) and ramp into one side. Bit like the early game traps. Throw a ln extinguisher grenade at it to put the flames out every time it does its jump and flames come out of its nose. Then use a longness rifle and shocking tranq darts to KO it. Then place a medical stand next to it. With 50 narcotics and it will tame in less then 10 kibble in minutes. EASY. Ive tamed 8 in under an hour. Structures dont take damage and medical stand feeds the narco in keeping it knocked out.

It has giga torpor and a low health

Its a knockout tame

It eats meat

If you have one then go kill pyromane
