***************************************************************
This year, the quest offers a base maximum of 7 Party Favors for a 5-star completion, as +SteelStar's Hound companion awards an extra point if killed. (
Bug: If run at level 36 or 37, the challenge is currently only providing favors as if run on level 35.)
Anniversary Party CR Relative to the highest level party member:
- At-level: 7 Party Favors
- +1 (or +2) levels above: 10 Party Favors
- +3 (or +4) levels above: 11 Party Favors
- +5 (or more) levels above: 13 Favors (the maximum)
Running the quest at a CR below the level of the highest level member will result in fewer Favors, but as this is an intentionally "easy" quest, that is not recommended, except perhaps solo.
During bonus weekends, the bonus is rounded
down. So, running at 5 levels above during a +30% bonus gains {13 + 3.9} = {13 + 3} = 16 favors.
Aside from Collectables and drop-loot Minimum Level, there is no reason to run the quest at +2, +4, or more than +5 above the level of the highest level character in the group, as no additional Party Favors will be awarded. However, you can earn a very nice first-time XP award for a 5 star run, so it is recommended that your first run of the Anniversary Party challenge should be at the highest CR that you can manage within your group. At epic, level 20 characters can get full experience with level 30 characters in group without overleveling penalty, and will award ~120k XP at CR35 for a 5-star run (only with the first-time bonus though).
