Thundercaller Bard casting the spell Shadowbard

[ckdragons]

How does the spell shadowbard interact with a Thundercaller Bard with the Thunder Call ability? Does this mean the bard can use Thunder Call twice (once by him and once by the shadowbard) each round?

Technically? The copy automatically follows you, but says nothing about its action economy. I would assume you have to use your move action to direct its targeting, otherwise it would continuously Sound Burst the same area over and over again.

I would assume so yes, it seems the intent is that the shadowbard is just a copy of you using the performance and the intent is things like targets and numbers don't require any special input from your pc.

A vanilla Bard could select Deadly performance as a legal option for shadowbard and they would be required to target someone different every round, the only action that's ever required from the player is a move to change to a different performance.
