The Legendary Raids are a great way for beginner players to unlock some really powerful legendaries. Glyptoceras has a really powerful moveset ,including a Critical Rampage. Indominus feeds a ton of hybrids, so you will need a mountain of its DNA. Rinchicyon is the best of the bunch, with a great balance with a moveset and stats. And then there is Scorpius Rex, who, while being a legendary, can be a devastating opponent in both tournaments and PVP. Good Luck, Beginners!
