Taming Results
Use the calculator results to plan your tame - they show the exact time, food quantity, and bonus levels for the Tek Rex based on your settings.
Required Narcotics
Use the narcotic calculator to determine exactly how many Narcotics, Bio Toxin, or Narcoberries you need for the Tek Rex. Your options are Narcotics (40 Torpor), Bio Toxin (80 Torpor, best efficiency), or Narcoberries (7.5 Torpor, cheapest but slowest). With Torpor draining at 0.73/s, don't wait until the bar is nearly empty to apply narcotics.
Starve & Torpor Timers
The real-time timers below help you monitor Torpor drain and Food depletion during the tame. Starve taming is recommended for valuable high-level Tek Rex: let the Food stat deplete first, then add food. This way nothing is wasted if something goes wrong.
