Look at manticore go to addmen commands type in: KILL and watch it fall DEAD! ☠️ If you know how to cheat and want to get the job done quickly this tip is for you! If this tip didn't work then you probably didn't do it right.
Bring around 6-7 or more rexs and when it lands everyone get around it and trap it. Deathworms will come and knock u back but just keep moving forward slowly so u dont get pushed out. Even when the rock golems come don't stop hitting it. Goodluck boys :)
When fighting the manticore a good strategy is bring in high level Rex's with good saddles and circle the manticore it then becomes pinned allowing you to kill it without it flying all around .... watch out for the poison it shoots at you though it will kill you off your mount like the poison wyvern ..
