I am in need of a bit of clarification if someone would be so kind. Firstly is the Bard Masterpiece I am referring to:
__________________________________________________________________
Song of Sarkoris (Oratory, Sing)
Source Blood of the Ancients pg. 31
You recite inspirational lines from this epic poem commemorating the final stand at Storasta, keeping defiance alive even in the face of certain death.
Prerequisite: Perform (oratory) or Perform (sing) 10 ranks.
Cost: Feat or 4th-level bard spell known.
Effect: When you complete the performance, all allies within 30 feet gain an attack of opportunity when reduced to negative hit points, or whenever a foe deals hit point damage equal to or greater than its Hit Dice, for the duration of the performance. The attack of opportunity can be made against any enemy within reach; it does not have to be against the source of the damage, and does not count toward your allies’ maximum attacks of opportunity per round. This attack of opportunity is resolved prior to the enemy’s attack, but the triggering attack is still resolved even if the enemy is killed or incapacitated.
Use: 2 bardic performance rounds per round.
Action: 1 full round.
___________________________________________________________________
My initial question arises from the action economy line. It states "1 full round". Is that meant to be a "full round action", or a "1 round action". Does the Bard start the performance and on the end of her turn it begins or does it not begin until the beginning of her next turn?
Further more, if a character that is affected by this Masterpiece is attacked by four creatures and they all do more than the character's HD that character gets an attack of opportunity on all four or is it meant to be once per round? This seems extremely powerful if it is the former. I know it states "whenever a foe deals..." it just boggles my feeble mind is all.
The wording also contradicts itself.
"When you complete the performance" implies the performance ends, yet it gives you a usage cost of "2 bardic performance rounds per round".
Any help understanding this would be wonderful.
