I'm sure I'm not the only one to have noticed, people are confused about how the Bravery Bonus works, how it stacks with other bonuses, how to earn it in a quest, and what will impact their streak. Initially, I answered a few questions in another thread (further down this forum) and realized that there were a few immutable rules currently governing the Bravery Bonus and its behavior. Below are the few that I've managed to nail down and verify through repetition and corollary reports.
Rule 1: Bravery Bonus (hereafter referred to BB) only applies to quests within 2 levels of your toon as determined by said quest's 'Normal' difficulty challenge rating. (IE: If toon is lvl 6, BB applies to quests lvl 4 and up)
Rule 2: BB applies only to the FIRST run of a quest.
Rule 3: Subsequent runs of the same quests after the FIRST do not impact BB. (IE: Multiple elite runs of the same quest do not stack with each other. Also, running the same quest E/H/N applies only the first Elite run to your BB)
Rule 4: BB stacks up to 5 times. (That's a total of 25% for hard or a total of 50% for elite and only the highest of these two applies)
Rule 5: Once you have exceeded the 2 level restriction, running a quest for the first time on Normal will not impact your BB. (IE: You're level 10 and decide you want to go farm Chronoscope, a lvl 6 quest. It will not impact your BB because Chrono's normal diff rating is lvl 6.)
Rule 6: Completing a first run of a quests at a difficulty below your highest streak will reset that streak to the level at which you complete said first run. (IE: You complete 5 quests on elite, giving you your 50% streak bonus, the following quest you complete on hard. Your elite streak is reset to 0, but you maintain your Hard streak and your 25% streak bonus)
Rule 7: BB is an individual bonus based on your toon and the quests completed by you on it. (IE: If you are Level 9, completing Elite Tempest Spine CR10, grouped with players ranging between lvl 9 and lvl 12, the BB will be applied and your streak counter will continue)
Rule 8: BB will ONLY be applied if ALL toons in the quest are 2 levels above its Normal Diff CR or LESS. (Using the example from 7, the same group of 9's-12's, could not complete Elite Haywire's Foundry CR9 and still receive BB or streak bonus)
Rule 9: TRing resets your Bravery bonuses and streaks. All quests are considered "Never run before". (This allows you to earn BB streaks on ALL quests, regardless of what you ran prior to your TR)
Rule 10: Only actual and completed quests impact BB. Challenges, slayers, party wipes, recalling before all required objectives are completed, will not impact BB, nor will any 'Quest' which involves simply stepping in, talking to an NPC, and leaving... A'la Return to Delera's Tomb.
Please feel free to correct me if I'm TERRIBLY off base, but these are the truths that I've managed to divine from my runs since BB was added.
As I come across new ones that I'm able to verify, I'll adjust the above accordingly. If you have contradictory reports, please share it so I can try and verify it as well. Think of it like Mythbusters, Bravery Bonus edition.
And knowing is half the battle... GO JOE!!
OP Note: Here's hoping the Mabar event gets a similar tweek to the fix given to CC at the last minute.
