This quest pits you against a Rathalos and an Azure Rathalos, who haunt the normal areas in the Ancient Forest that the Rathian and Rathalos typically occupy. If you’ve been keeping your gear upgraded to the point where a high rank Rathalos isn’t too much trouble (and ideally you have armor with Fire Resistance and Poison Resistance skills), then this battle shouldn’t really be any more trouble than the Rathalos and Rathian in the quest Redefining the Power Couple was, and for many of the same reasons.

Again you’ll find yourself presented with conflicting approaches to the battle, since the Rathalos and Azure Rathalos are likely to meet up at some point. You can fight them both at the same time, attempting to dodge between them so they hit each other (while cautiously attacking as opportunity allows, of course) or focus on them one at a time, driving the unwanted wyvern away with Dung Pods if they interfere. Either way, Flash Pods will be especially useful in this fight, as both are avid fliers, and a single, well-placed Flash Pod can send both wyverns crashing to the ground.

As always, search for tracks ahead of time to boost your Scoutfly Level, and when one is near death, use traps to capture the moribund monster to save yourself some trouble. Return to camp when you need to restock, heal, or eat another meal, and be sure to buff yourself with Demondrugs and Armor Skins. Going out of your way to recruit a Grimalkyne can’t hurt, either. Once one of the two Rathalos are defeated, dispatching the second one should be a comparatively trivial matter.

Defeat the two Rathalos, then return to Astera and talk to the Armory clerk to obtain your reward - the Challenger Mantle.
