Limitations

The Summons use the Find Familiar spells as it's backbone which is what prevents players from Summoning multiple copies of the Aeons. So, if you use mods that alter Find Familiar or would like to multiclass with another class that uses the Find Familiar spell, know that you'll probably have compatibility issues or at the very least won't be able summon an Aeon at the same time as a Find Familiar summon.

Dynamis Shield and Omega Intuition don't work while wearing any kind of armor or shield.

If you know your gonna play as an Al-Bhed I strongly suggest that you put stats that are in Charisma into Intelligence as I have not devised a way to alter Ability stats after subclassing into Al-Bhed that don't include other mods or using Withers.

I'm currently unaware of any mods that would cause Incompatibility Issues and like my previous mod there shouldn't be many since my Mod only uses resources from the base game that have been copied and altered.
