Actually the Basilisk only eats Rock Drake fertilized eggs. The wiki says that it should also eat other fertilized eggs, but currently it ignore them. Probably it's a bug, for now feed it Rock Drake eggs
Many people think I’m vicious, unfriendly, and dangerous. However, I’m really just angry I can’t get any good type of cuisines. Survivors just make up the lost nutrients! I crave a good exotic dish. I never have time to go scavenge for them however (Fine, I’m just too lazy to get them myself), and hence why I will love anyone or anything that would give me these. As a part of the Serpentes family (Snake family), I love eggs. For my preferences, fertilized ones. However, I need something with more punch for my larger (and more hazardous) digestive system. There are 3 specific flavor types I love. Radioactivity charged tanged egg with a mild rocky flavor, a very spicy but melts on the tongue kick, and finally, a crunchy, bitter electronic, but still very flavorful, metallic egg. (Hey, don’t look at me like that, everyone has different taste preferences!) Of course, this is the rock drake, magmasaur, and voidwyrm fertilized eggs. Please, I’ll love you forever if you feed me these. (I might think of you some random attacker when I first see you, so please avoid my eye contact and drop the eggs for me, don’t worry, I’ll find out who got me this treat later) Thank you tasty- I mean generous survivors for reading this!
Getting it to eat the egg is pretty easy, just throw an egg on the ground, then get close enough to it (maybe on a fast tame) for it to come out of the ground. Run away towards the egg with the basilisk following you, and then keep running until out of targeting range. Heading behind a giant rock or metal plate helps. Once the basilisk stops following you, it’s will head directly over to the egg and eat it! I got two basilisks this way today :D 🆙 if helpful :)
AS OF FJORDUR UPDATE: basilisks can now eat fertilized wyvern eggs! I got a 145 to down ONLY wyvern eggs and it completely tamed! It might hurt the taming effectiveness some but I’d say it’s still worth it if you’re not ready to get rock drake or magmasaur eggs! I did this on PS4 with no mods, meaning it should work on at least other consoles and hopefully PCs too! Up if you want fellow survivors to see this so they can stop risking their butts in the magmasaur and rock drake caves and have an easier time nabbing some wyvern eggs! (I know it works with fire and poison eggs, I haven’t tested other variants)
