Thought I would throw this out there because there are undoubtedly other players out there wondering why world/dungeon bosses will drop no loot above green caliber. There is the chance that a boss will not drop high quality loot, I know this.

After experimenting extensively with the crab boss in Fane of Kapprima (using the spikes to damage the boss/and to not damage the boss), we have noticed that if the boss is hit by the spikes or takes any damage from them, he will not drop any loot above green quality.

To explain further, the spikes do a flat ~4% to the boss when it is impacted. Since the spikes encompass a significant mechanic to the fight, the chances of the boss being impacted by them is very high. It was much easier to avoid the spikes than it was to pull the boss away from the chance of getting hit by the spikes. With 8 kills after the boss was impacted by the spikes at least once, nothing above green quality loot dropped. The 2 times that we killed the boss while actively making sure he never got hit by the spikes, we received superior quality loot.

To further compound this, I have tested this on World Bosses where they are damaged significantly (over 5%) by another BAM. The same results occur. Even 1 more example of this would be the exploding barrels in Akasha's Hideout (also on a crab boss). This was only tested twice, but both times that the boss was impacted by an exploding barrel, the loot quality was not above green.

Now, I am not 100% sure that the cause of faulty loot tables is in fact the damage received from other BAMs/Mechanics, but it is safe to say the fail safe against players using BAMS to kill BAMS and get loot is misbehaving and preventing players from getting loot in instances and off of world bosses (just because they happen to aggro more than 1 BAM and they hurt eachother).

This seems pretty important.

Using the fight mechanics to defeat a boss shouldn't be reducing loot drops.

Another one for the bugfix pile.

Unintended design choices making certain fights very unrewarding.

Meh, that's really lame.

This needs to be fixed.

That's probably why Akasha hasn't dropped anything in a few of my runs with levels 51-53 in the party? Hit by the exploding barrels?

GG EME/BH.

Korean game.

Bad RNG is Bad rng? While it may affect the loot its not nearly as much as you are saying. In my 4 runs of kaprima with spikes ALWAYS being used i have recieved a superior off that boss 3/4 times. Obviously differences can be seen sometimes when you contribute less damage to a boss then its full health but not to the extent you are claiming or i would not have seen anything drop.

Probably just your bad luck.

Last run, boss got spiked multiple times, got gold plate chest and gold leather gloves...

Despite your finding after 10 kills, Vanubial's findings differ. Meaning that you really don't have nearly enough sample data in order to form a solid hypothesis on the loot drop quality. After 100, or better yet 1000 such fights you may get at lest some trending data. After 10000, we might really start getting some solid drop rates and percentages.

tl,dr: Your sample size is too small to make any sort of conclusion as of yet.

I'm hoping this isn't accurate as one of my favorite ways to complete BAM quests solo is to pull 2 of them and let them continuously knock each other down while whittling away at them. Doesn't seem like abuse to me, seems smart.
