I killed Captain Nebula after Organization XIII told me to, and when I went back to Hank Hill, he told me to speak to spongebob for the answer to the puzzle on the back of Chronos, wherein I found a merchant who sold me the Gjallarhorn, which was just a bonus. The merchant, who's name I never caught but who's T-shirt read "the first of the wise men", told me to go and defeat the Goliath Pinhead in the depths of the hellmouth. So I killed Pinhead, who WASN'T actually a Goliath (DAMMIT BUNGIE, FIX YOUR GAME), and when I emerged from the depths of hellmouth, Shrek told me to kill 500 guardians with void weapons and a kilo of heroin (not the drug. Shrek peeled 2.2 pounds of flesh off of a heroin) After that, Grundy and Bane told me to kill xylor the unwed, phogoth and guy Named tesla for it. Totally worth the hours it took.

I got mine from the mission were you team up with xur and master rahool and kill the sheep of squierlington and defeat the 22 monkey men and save the 13th dimension and master chief gives it to you and then flys away on shreck's back

Laughing so hard at fools thinking xur doesn't sell bounty weapons. Every 7th Monday(7th day of the week, destiny weeks start on Tuesday) @ 7:07 xur spawns somewhere in the tower with a random weapon for 77 seconds.

Got mine from nightfall, I saw Eris morn selling one the other day tho, I forget how much she was selling it for though

When I first came to this thread I had to reread it twice

I got my Thorn when I bowled a 300 against Roman.

Got mine from Varkis. He also gave me Invective from a package.

Got it from patrol

Signed

Got mine from the gorgon chest in VoG

I killed xylar and it dropped for me at 567 attack.

Got mine from Nightfall [spoiler]For new players you get the thorn from killing randal the vandal it has a 0.5% drop chance :)[/spoiler]

I bought mine from the broom bot ( ͡° ͜ʖ ͡°) one mote of light

Hold up. I thought the only way to get thorn is by doing the bounty?
