At lvl 72 with flak armor on, a lvl 5 Troodon knocked me out with one attack at night. Last thing I saw was those glowing eyes before passing out. My Guess is that they attack vital organs. Luckily my Doedicarus was up for a game of baseball and launched that little devil out into the stands.
Went to go grab a drop during the night on my dragon. I was wearing full Master Craft Flak Gear and two bites from these little sneaky bitches and I passed out. Luckily my dragon was on nuetral. Unluckily that it's fire breath roasted me too. Lesson learned:
Burn everything on fire before you get off your mount...
Step 1: make a taming pen.
Step 2: put a lvl 80+ baby wyvern into the pen. Knock it out if you want to and lower its health down to almost 0.
Step 3: Drop troodon inside while its eyes are glowing.
Step 4: Enjoy your tamed troodon
In order to tame a trodon, you must sacrifice a tamed animal, beter during the night, and the bigger the tame, the better the taming effectiveness, what i suggest ia that you breed baby dino's and trap the trodon before hand,the best to sacrifice to the trodon is a giga and i suggest a baby for a low risk.
I just tamed a 120 one.
What I did was I had 3 150+ Baby Brontos in cryopods and a high durability shield and stimulants in my hot bar. Throw the baby Bronto out of the cryopod (with cryo sickness) then let the Troodon out of the cage. Kite the Troodon around your unconscious tame and if you get hit eat a stimulant. (Stimulants prevent you from gaining torpor for a couple seconds as well as lowering your torpor).
When your tame dies throw out your next one and kite around it the same. Do this until it tames.
You need to do everything seperate because for whatever reason if it hits another tame at the same time as killing another one it will reset the xp gain and you won’t be able to tame it
