Although this quest may seem to be quite a chore after fighting both of these monsters individually, it’s honestly not that bad. Unlike the Rathalos and Azure Rathalos, the Lavasioth and Uragaan don’t share much of a range. Both may meet in AREAS 11 and 7, but if they do, you can just hang back and let them fight it out and rejoin combat when they’ve separated… or you can use a Dung Pod to encourage one of the two to leave. Tackling the Uragaan first in the non-fiery areas (AREAS 2, 6 and 5) may be the best choice, after which the Lavasioth shouldn’t be much of a problem. Since both monsters are weak to the Poison ailment, bringing along a poison weapon should be a no-brainer.

After defeating this magmatic pair of monsters, return to the Armor clerk in the Workshop and she’ll hand over the Fireproof Mantle, as promised. This particular tool will come in handy rather soon, so you may want to go out of your way to obtain it.
