Damage Required to get Brilliant Blackwyrm Chest?

[llIll]

If it is 10% of the Blackwyrm's hp to get the regular one, what does it take to get the brilliant?

1% for regular, I've heard both 2% and 3% for brilliant. 10% for regular would be just silly, there wouldn't be hardly anyone at all getting any chests per kill.

I'm not too sure about the dmg, but I do know that you need to get at least 13 prestige point for it. For 12 you still get regular one, but as of 13, you will get Brilliant. Or, if you hit her last, you will get your normal chest, and an additional Brilliant one.

It is 1% of the Boss hp to get a chest. Prestige is not a good metric to determine reward because it depends on how many people it was divided between. If 100 people did 1% damage then you would only receive 4-5 prestige. Anyways, fyi on weekends you get a tier up on the BW chest drop. That means that 1% will give you a Weekend Chest, if you do damage for a Weekend chest that gets bumped up to Brilliant, if you would regularly get rewarded a Brilliant chest you get bumped up to a Brilliant Weekend...
