The additional effect for Fire II does not match the action it does.
Current description: "Additional Effect: Grants Astral Fire III or removes Umbral Ice"


Here is what happens when under Umbral Ice and using Fire II

(gif description: gif of Fire II being used while under Umbral Ice, changes from Umbral Ice III to Astral Fire III)

If this is what Fire II is supposed to do, then the additional effect should read "Grants Astral Fire III AND removes Umbral Ice."

Additionally, Blizzard II's additional effect reads "Additional Effect: Grants Umbral Ice III and removes Astral Fire."

While on this topic, the phrasing for the additional effects of Black Mage are rather awkward.

The order reads better when stated as (example)
Fire III, Additional Effect: Removes Umbral Ice and grants Astral Fire III.

This phrasing makes sense with the order the actions, Umbral Ice is removed and then Astral Fire III is applied.
