So, if I have both of the above will each round of A. Luck work for two additional rounds if I do not reactivate it the next round? Can I then activate it again after those three rounds, spend one round worth, and get two more on top of it again. An Archaeologist with a 16 charisma would normally get seven rounds of luck, but could turn it into 21 rounds with Lingering Performance. By adding the Extra Performance feat this effective number of rounds would be 39. That's alot of luck!
Yep. That seems like the point of it, and the reason it was explicitly called out.
Called out by whom?
Doesn't Luck specifically say it works with lingering performance? Maybe that's dervish dancer.
Battle Dancer specifically calls out that Lingering Performance does not work with it.
Ah! Well that means Archaeologist's Luck works with it.
Per Lingering Performance: "Any other requirement, such as range or specific conditions, must still be met for the effect to continue."
Which means that limits on rounds are still in effect when it lingers. The feat is designed to carry on bonuses (barring any other requirements, like rounds available) after you would normally cease your performance.
Was there any real reason to resurrect 6 threads, several of which were years dead, with the same post in each thread?
