My best tips to offer are,

1. If you have an argy use it to pick up one(it won't attack you when you pick it up)

2. Carry it to a safe place where you can ko it or where a trap is( I just chased it and and used a crossbow)

3. Feed it simple kibble for easy taming time( I used berry's and it tamed pretty quickly)

4. Watch over it and don't let anything kill it

5. Bam put a saddle on it and ride around

6. Males can attack but females can't

7. Have fun

Just get your longneck and two tranq darts, hop on your argy with a friend on his/her argy and go to redwoods, get super close and shoot it, then get 20 tintoberries and feed it to the Megaloceros, the males have antlers and the females don’t have antlers, up this so all can see

Funny story, just recently I tamed myself one of these. Before I left base I crafted the saddle for it in my smithy then made my way to the snow biome. (Yes, I know there is deer in the redwoods too I just didn’t want to have to deal with raptors and terror birds), anyways so I tame the deer, and put the saddle in its inventory, only to realize I crafted a megalosaurus saddle instead of a megalaceros saddle lol 😂

Information All that I know: 1. These things are speedy as heck. You need to be fast to catch one. 2. They spawn in Redwood, so be careful. Redwood is much harder to survive in, in my opinion. 3. You have to feed it berries, or anything avalible around you that is a berry, if you don't have one. 4. These things can eat eggs if they are tamed. Fr, literal dino eggs if they are tamed. 5. You got to be strong, because these deers also can have health that can take long to take down. 6. Try not to kill em, they make good pets in my opinion. -Mobile, 2022, TinaZ.
