A handy tip to see if you need arrows or darts is to find out how much total health your doedicurus has and then choose your weapon to knock it out. Then using Dododex, see how many shots it takes to knock it out and then click on the weapon to see how much damage it does. Multiple those 2 numbers and if your answer is the relatively close to the health stat, choose a longneck instead. Example: I have a level 120 I want to tame. I have a crossbow that takes 40 shots to knock it out and does 150 damage per shot 40x150=6,000 so I switch to darts. If I had a level 100 and wanted to tame it with a crossbow that did 90 damage and took 50 shots to knock out 90x50=4,500 which (let’s pretend mine had 7k health) is less than 7,000 so I can knock it out with a crossbow. Remember that the examples at the end are NOT accurate just the idea. Happy taming!
