Just a note: it might be worth taking a moment to update the unit graphics in this mod. Specifically, the spellsword and planeshifter are missing _AMURITES at the end of their earlyartdefinetag tag. It should look like this:
<EarlyArtDefineTag>ART_DEF_UNIT_SWORDSMAN_AMURITES</EarlyArtDefineTag>
but it's:
<EarlyArtDefineTag>ART_DEF_UNIT_SWORDSMAN</EarlyArtDefineTag>
As it is, we get ugly default graphics instead of shiny, fireball-in-hand Amurite graphics.
For anyone looking to do this themselves, remember that this is technically a modmodmod so the civ4unitinfos.xml directory is:
Sid Meier's Civilization 4\Beyond the Sword\Mods\FFH Wild Mana\Assets\Modules\NormalModules\FFHPLUS\Civs\Amurites
<EarlyArtDefineTag>ART_DEF_UNIT_SWORDSMAN_AMURITES</EarlyArtDefineTag>
but it's:
<EarlyArtDefineTag>ART_DEF_UNIT_SWORDSMAN</EarlyArtDefineTag>
