You’d probably be looking at Flare Burst as your new Fire damaging skill. Silver Rathalos has plenty of chances to be an unanswerable beast until then.
Its weakness is Water, which at this point in the game’s lifespan, does not have many strong Water Monsties. This Monstie’s stats encourages you to make it your “main” offensive Fire Monstie, with Fire Attack at 10 – ties with Teostra – and Crit at 8.
