I found a level 112 Argent and kited it up to the top of the volcano with my Ptero. The combination of Argent talons, hyperthermia, and dehydration almost killed me, but I managed to knock him out with tranq arrows from a prim crossbow. I had to tame him with regular meat unfortunately, as my prime meat spoiled, but I still got 98% efficiency (I play singleplayer woth boosted settings). Feeling pretty happy about it, not every day I get a 167 Argent.
