Okay, so I'm under the impression that every exotic in the game has a secret perk/ability (like Legendary weapons, in Diablo 3 and in the Borderlands games). Here are the ones I am 100% sure of: [b]Gjallarhorn[/b] has premature detonation on the rocket (always killing myself because of this) [b]Thunderlord [/b]has a AoE damage effect every so often when you kill enemies (also a nice [i]boom [/i]sound when it happen) [b]Truth [/b]allows you to carry more heavy weapon ammo (I can carry 8 rockets rather than 7) Here are a few speculations I've picked up: [b]Feedback Fence[/b]'s armour brings you back to life if you are killed by a melee attack (mentioned in [url=https://www.bungie.net/en/Forum/Post/134617629/0/0]this thread[/url]) - might have to be a certain melee kill or have the melee charged on your character - this is just speculation, I've not come across it. Could be lag + transfusion. I don't see why they would add one to some but not all, it'd truly solicit the weapon being called "exotic" and make them one step higher than legendary ones. I'm fairly convinced there are more, I just haven't spotted any yet.. :) Have you guys noticed anything else? I'd love to compile a list of all of them and I'll add yours to the list if you know of any! Edit: I am aware that SUROS has glass half full, I was on about it having more and more damage the further you eat into the second half of the clip (even more than a normal glass half full). Thanks for all the observations guys! This is awesome. I hope we can find more! I'll be updating this thread tomorrow with your suggestions.
