Kill these to gather the mats to build the blade gauntlets from the trailer. Taming takes element and time if you see element nodes swarms are never far away. Bug spray will not work but you can lure these on a PT to a trap with rare flowers. These flying cinders are something else.
Frog has the most damage against them and then torch below that. Water can make them avoid you but they can also be outran just by walking if you start moving as soon as your targeted. Running gets you away faster tho obviously.
