So if you want to tame one of these on rag they spawn nere highlands on the beach use a stone 2bye2 with stone door frames and an argentavis.pick the megalania n drop em into the trap then use darts or trank arrows preferably darts cause arrows sometimes kill em.bring a good amount of narcos if your goin for a high lvl cause there torpor drain is really fast. The food I recommend using is mutton since your right next to highlands. Hope this helps
