Trial of the Magians - Axe Trials  

Skeggiold Trials 344 & 1332

Trial 344: Bomb-type monsters in Earth day/weather
Trial 1332: Arcana-type monsters in Earth day/weather

Both these trials can be done in The Eldieme Necropolis [S] fighting Ignis Djinns. If you are between levels 75-78, you can also do these in Batallia Downs [S] . In the downs, you get just as much Earth (Dust Storm) weather as you do in the Necropolis. In the northwest part of the map, about 7-10 Djinns spawn checking Easy Prey to a level 78 (some checking Too weak). This can be a better place to do this trial circa the levels mentioned, due to Ignis Djinns being tougher fights at that level.
