1.[i] Complete The Summoning Pits on the Moon.[/i] Pretty simple. 2. [i]Earn 500 points by killing Hive enemies on the Moon. (A normal enemy is worth 1 point, a Major is worth 20, and an Ultra is worth 50.)[/i] Just do the "We've awoken the hive!" Level. 3. [i]Use Void Damage to defeat Guardians in the Crucible. Death will slow your progress. Requires 500 points. 5 points are gained per kill, 2 lost per death (meaning that progress is made as long as the average ratio of void kills to deaths is sustained above 0.4). [/i] This is said to be the 'hardest' part of the bounty, but is actually fairly simple once you get the hang of it. These are some set ups i recommend: [b]note: if you have a void primary, use that[/b] Warlock: What I used: I used Voidwalker, with Bad Juju, void sniper, void rocket, Axion bolt grenades (+bloom) and the soul rip melee (I didn't have a warlock exotic armour at that time) What you should use: (use grenade of choice, for option 2,3 use the right grenade for exotic perk) Voidwalker with: Bad Juju + Obsidian Mind + max intellect or Noting Manacles + max discipline or Voidfang + Max discipline You can combine any of these with blink + (void) shotgun, which will make it a lot easier, use a proximity void rocket launcher (or machine gun if you can go on a streak) Titan: What i used: defender Titan + full auto (void) shotgun (blue rarity) + blinding bubble + magnetic grenades What you should use: Defender Titan + full auto (void) shotgun + magnetic grenade + (the armour that gives you two grenades + proximity void rocket launcher (or machine gun if you can go on a streak) Hunter: (I haven't gotten the Thorn bounty on Hunter yet) What you should use: Blink (void) Shotgun + proximity void rocket launcher (or machine gun if you can go on a streak) + max agility (Bladedancer) It is probably the hardest to do it on the Hunter, but still fairly easy because blink + shotgun is easy to 'master'. 4. [i]Obtain an Infusion of Light from The Speaker.[/i] This will cost one Mote of Light. 5. [i]Talk to Ikora Rey.[/i] Simple 6. [i]Kill Xyor, the Unwed.[/i] Xyor is found in a level 26 The Summoning Pits that is only available while this phase of the bounty is active. The Epic modifier is enabled, and matchmaking is not used (so get some mates together or solo it) Get Phogoth down to about 25% then a ship with Xyor will spawn. You must kill Xyor before Phogoth. 7. [i]Return to The Speaker to claim Thorn.[/i] Congrats you got the Thorn! Hopefully this has helped everyone. If you have another guide for the 500 void kills part, comment it bellow and I'll add it.
