Be prepared to have at least 3 of each apex drop. Ive tamed 2 of them, a 140 stallion and a 145 mare, and both asked for giga hearts and alpha Rex tooth. If you don’t have them then be ready to fight with a high lvl carch or two. Gather your tribe mates, drop the alter as soon as you can when it gets dark, and have your apex drops ready. Good luck!
