10 people 10 rexes maybe a yuty but look up and suround it will trap it.

Use 20 decent Rex’s, a pig or two, and rocket launchers.

Bring Therizinos instead of Rex’s, since herbivores take reduced damage from the fire, and can eat sweet vegetable cakes to regen health quickly. Take about 17-18 theriz, 2 hell pigs, and 1 yuty as well as an OP rocket launcher or shotgun, or substitute 4 theriz for allo’s to get the bleed attack.

Everyone here talking about Rex’s this and Rex’s that is foolish. Maybe 4 Rex’s to tank a little and the rest Mut Theriz packed full of Veggie Cakes. The fire melts the Rex’s even with ascended saddles. And all our Rex’s were 35k hp+.

16 Rex 2 pigs and yuty hard boss fight on rag is so easy when u get the 10 riders 1 guy on a pig with other following make sure it's full food and has food in inventory... Rex's must be 30k health and 600+ attack JM saddles or better is advised 1 yuty rider high standards to keep all boosted .. everyone else on Rex . Yeah b make sure pigs DO NOT Let anyone else whistle them pigs for healing not attacking

Use Dragonrend to make it land, then punch and Fus Ro Dah it until it dies

18 Rex’s 1 yutyrannus with rider, 1 daedon with rider, rider on 1 Rex too command Rex’s attack and passive.👍🏻 That’s how I took out the dragon and manticore. Good luck😀

Boys the new method is to have 5 theriz atleast 3 manas and 2 megaloceros (Male) with 90 plus armor saddles. 20-25 cakes on all the herbivores. One megalocero goes under the dragon, the other one is for backup and the megalocero will keep the dragon distracted and will barely take any dmg. Both megalocero riders along with the theri riders have above 240 dmg pumps and the Mana riders just use their freeze attack. Everyone should have 2 sets of flak atleast. Calien soup. Btw you can shoot the dragon while on the back of the megaloceros. We had 6-7k hp on the megaloceros and put points in some weight. When the megaloceros has the dragon semi-trapped the theri riders can jump off and pump. Sometimes the megalocero rider will have the dimorphodons on it so run up to it even if it has the dragon on it you can kill them with the theri. GL Jan 2019 method I used.

I recommend at least 5-10 lv 100+ dodos but if you want a challenge 15-20 high lv rexes work to

Use rinos and a yuty 9rino 1yuty 1 person with a gun easy

You know that you cant bring stuff like gigas into boss fights right? Rexes are the biggest mount you can bring i think

Our rexes had 80k HP and 6k% damage which is 2k per bite. We had lost 3 of rexes. Beta Dragon.
The Dragon isn't the only thing you should worry about. The dimorphos will kill you off your mount if you don't have a good armor. It is better to bring a lot of people to mount rexes, as about 2 out of 3 rexes died in lava. They just stand in lava and bite the Dragon. Reaper could be good if you have one(for killing dimorphos), but prepare to lose it - Dragon ignores its natural armor. Good luck, survivors.

Alpha dragon on rag is easy the island is another story. It will destroy Rex's with 40+k hp and ascendant saddles. Keep out of the lava

I would recommend two Daodons about 18 Rexs andirons you want sure use a Yutyrannus also bring rocket

Just bring a few decent level dodos and you’ll be good

Level 999billion dodo bird or a level 999billion dodorex

Just get like 15-20 high lvl imprinted rex's and let them do the work, u may have to whistle attack target.

Use a op velo i did it did 470k damage on fibercraft i one tapeed the manticore and the dragon

1 yuturanus 10 therizinos 5 Rex's 2 daedons and 2 velonosaurs

Bring 15-20 rexes and with 30000 hp and 1000 melee. Easy boss battle
