All you really need to do is grab it with and Argy and trap it then tranq it but be careful when you tranq it because it will knock you out and kill you. It is a very good tame to because it is very fast.
100% melee damage is 20 base damage with beelzebufo sweep attack = 60 torpor over 10 secs. A second sweep attack within that 10 secs will only deal additional damage. 1000% melee damage will do 600 torpor over 10 secs with sweep attack :)
Everybody’s making it too hard are you are you need is to kill jelly fish get the biotoxin then leave it out in a tame cage knock it out with a slingshot give it some meat I give it some of the biotoxin to keep it knocked out you got yourself a oversized toad
These oversized toads are easy to tame. All you need is a bola, tranq arrows and meat to tame them. Their food drops faster than their torpor, so you won't need that much narcotics. Be careful not to tame one if there are others nearby.
