How to cope with troodon existence:
Step 1: Learn to create rope and tie a noose
Step 2: Learn and build a chair
Step 3: tie said noose to nearby tree branch and place chair underneath
Step 4: wrap the noose around your neck
Step 5: kick the chair beneath your feet
Step 6: Accept the death for it is a better to go then to watch as those glowing eyes mock you as they prance around your unconscious body for days. It never ends for they only kill when they no longer find you amusing.
Step 7: Put down the controller, turn off your console and go outside. Realize why you play this game to begin with.
Be aware if you try to breed one of these, they occasionally won't eat the food in their inventory and need to be force fed. I have seen this in the juvy/adolescent stage as well so don't assume they will eat from the trough.
Build a hatching pen as you would a taming pen hatch a level 120 plus wyvern and let it sit in the pen then find a high level troodon and drop it in the pen I recommend hatching 2 wyverns but that is the best way of taming them
Use a trap to keep it in one location. Wait untill nightfall. Knock out your tame after setting it to nuetral and stand on it. The Troodon will hit it trying to attack you. To avoid getting knocked out, use a cheap Riot Shield. They bounce off.
