For full Troodon taming details, download the taming calculator app.
To tame a Troodon, you must let it kill your tamed creatures. The effectiveness of each creature is determined by how much XP is gained by killing them. Since XP gain scales with a creature's level, higher level creatures are more effective. Babies and adults provide the same amount of XP.
To prevent your sacrifices from killing the Troodon, you can tranquilize it and/or weaken it yourself before feeding it to the Troodon, however, you cannot set it to passive. Taming multipliers do not appear to apply to the Troodon. This calculator is in Beta. Be sure to add a bit of extra XP to compensate for any errors. If your results don't match this calculator, report it.
A level 150 Troodon must be fed 2,072 XP worth of sacrifices during the night.
