Does Svellsongr double a unit's Deflect, Assault, and Shield values, or does it create a duplicate that does nothing?

Ruling: Svellsongr doubles these values. The effects stack because Svellsongr copies the text, so a unit with Deflect 2 would have "Deflect 2" from its original text and "Deflect 2" from Svellsongr, combining into Deflect 4.

Nuances:

• The multiple instances of the same keyword combine into a single total value (e.g., "Deflect 2, Deflect 2" becomes Deflect 4, not two separate Deflect 2 instances)
• This stacking applies to Assault and Shield as well
