Make sure and bring a shotgun. If he ends up not landing enough its better to shoot him in the air and loose the element then not an loose everything.

15 rexs with decent saddles a yuty 2 deaodons

List of reqs: 18 high lv rexes 25k health and +650% melee, a yuty leveled in stam and health to survive and make everyone feel INSPIRED, a pig leveled in health and food (but mostly food), a couple (aka at least 3) prim gas masks, a decent shotgun with +100 ammo in case of no landing, also bring armor to keep cool/stuff to protect you (I use ascendant desert cloth stuff), med brews, stimulant, spyglass to agro things with accuracy, food, water, and any other buffs you want to bring along. Good luck

Carry stimulant with you..., Cause they manticore can knock down Your dinos very fast in battle, and that will be your end

Bring some flyers and a lot of rex
