Initiate of Mil stacks your Bard, Cleric, and Paladin levels for "determining which kinds of bardic music you can use (but not any other effect related to bardic music)."
From Smite to Song allows the sacrificing of a Smite Use to fuel an Inspire Courage effect.
"Your effective bard level (for the purpose of determining the value of the bonuses granted) is equal to your paladin level."
Now my question is, would Initiate if Mil allow a Paladin to multiclass into a Cleric or Bard and still be counted as a full Paladin when using From Smite to Song?
Ex: A Paladin 10 using From Smite to Song counts as a Bard 10 for how high his Inspire Courage Bonus goes.
Would a Paladin 5 / Cleric 5 with Initiate of Mil count as a Paladin 10 when using From Smite to Song?
By the RAW I want to say no since From Smite to Song explicitly states that your effective bard level is equal to your Paladin level, BUT since Initiate of Mil says your "Bard", Cleric, and Paladin levels stack I want to think that this also applies when using "From Smite to Song."
Thoughts?
