First, I want to appologize in advance if this is the wrong forum for a question like this, didnt know if it belonged here or in the advice section.
Now to the question, what do the sandman's lvl 9 ability dramatic subtext give that I can't get at lvl 1 with the new UM feat Spellsong ?
"Spellsong
You can blend the power of your performance and spellcasting.
Prerequisites: Cha 13, bardic performance class ability, able to cast 1st-level spells.
Benefit: You can combine your bardic performance and your spellcasting in two ways. First, you can conceal the activity of casting a bard spell by masking it in a performance. As a swift action, you may combine your casting time of a spell with a Perform check. Observers must make a Perception or Sense Motive check opposed by your Perform check to realize you are also casting a spell. This uses 1 round of your bardic performance ability, regardless of the spell's casting time."
and Dramatic Subtext:
"Dramatic Subtext (Su): At 9th level, a sandman can use bardic performance to cast spells without obvious visual or audible components while retaining the spell’s normal effects. Observers must succeed at a Perception check opposed by a sandman’s Sleight of Hand check to notice that the sandman is the source of the spellcasting (though spellcasting still provokes attacks of opportunity). The bard must use this performance for at least 2 rounds before casting a spell; otherwise he is automatically detected and the performance ends.
This ability replaces inspire greatness."
My understanding of this is that if I use dramatic subtext, my bard will have to stand around singing for 2 rounds before geting his hidden spell, but if I use the feat I could cast the spell instantly ?
