Ecumenical Caster

You have an ecumenical spirit. You have studied how different kind of magic access the Weave (the fabric of magic) and how diverse foci can intertwine and fold its threads.

• Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20*.
• You have advantage on Intelligence checks made to identify spells that a creature is casting using a focus or material components*. 
• You can use any arcane, druidic, or divine focus in place of the material components for you spells. This includes bearing a holy symbol on a shield as focus. 
• You learn a cantrip that isn't on your class spell list(s).

* Ignore the Dexterity option in the character builder; D&D Beyond feat builder doesn't offer Int, Wis, Cha option yet.  
** If using the rule in Xanathar's Guide to Everything, a character can use their reaction to identify a spell as it’s being cast, or they can use an action on their turn to identify a spell by its effect after it is cast.
