Tame a bunch and make a penguin farm for poly. Nine females to one male works great. Set up a bunch of ACs and have them on wander when the babies hatch club them. Free poly within the comfort of your own base!
Extremely difficult to tame. Best options are to bola it, and then use a longneck rifle with tranq darts. Otherwise trying to get it to fly into the side of a cliff and get stuff is the other option for a solo tame.
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 :)
