you can get combustion with any of the combinations of armors you have, to get combustion all you need is 3* fire armor or better (which you have) and 3* air armor or better (which you have). the best chance to get any good armor is abominable + armor of the infernal lord because you have a chance (very small chance) at blazeborne or tectonic mantle as well as the combustion.
