So, the revelation says:
Desire Sight (Sp) wrote:
As a standard action, you can learn the desires of any creature you can see within 100 feet, as if you had concentrated until the third round of detect desires. As usual for detect desires, the target can attempt a Will save to negate the effect. You can use this ability once per day at 1st level, plus one additional time per day at 5th level and for every 5 levels beyond 5th.
Is the ability supposed to work as if you had cast detect desires and concentrated until the third round OR does it only give the benefits described at the spell's third round effect?
That is, do you also get the first and second round's benefits (supported by "as if you had concentrated until the third round"), or are those effects skipped (supported by the general description mentioning only that you "learn the desires of any creature")?
Also related to the question of whether the revelation is supposed to mimic the spell or the spell's effect, do you activate the revelation as a standard action and keep it running for the spell's duration (concentration, up to 1 min./level (D)), or is it supposed to be a instantaneous effect usable as a standard action?
EDIT: This is the Detect Desires spell's description:
Detect Desires wrote:
This spell functions as detect thoughts, except you sense significant desires of creatures with an Intelligence score of 1 or higher, regardless of whether they are conscious or not.
Instead of Intelligence, the second round of concentration reveals each mind's Charisma score. If the highest Charisma score is 26 or higher (and at least 10 points higher than your own Charisma score), you are stunned for 1 round and the spell ends.
Instead of surface thoughts, the third round of concentration reveals the most pressing current desire of any mind in the area (Will negates).
Presenting a creature with an opportunity to fulfill a significant desire grants you a +2 circumstance bonus (or higher, at the GM's discretion) on Diplomacy checks to influence it.
