Best way to achieve a Ghallarhorn, is getting them from [b]"Nightfall, Raids, Trials and Legendary Engrams"[/b]. Every time you do a raid, you have at least 2 chances of getting the Gjallarhorn{Example: VoG Templar chest and Atheon, Crota Death singer and Crota}. PoE are a waste of time and Treasure Keys, i do not recommend doing them if your purpose is to get a Gally. "[b]Warning Math Ahead[/b]* [u]3[/u] Characters at least lvl34 x (2 Vog Exotic Reward x 2 Crota Exotic Reward + 1 Nightfall + 2 Gold Pck Trials + 1 Mercury Chest= [u]8[/u] Chances for Gally Drop) = [u]24[/u] Chances of Gally drop in total/per week. ≈ Heavy Legendary Engram = (1.82% Exotic Drop + (1/4 = 25%) Chance to get a Gally to Drop) = [u]0.0728[/u]% Gally Drop. *[b]Summary[/b]* - Complete Raids, Nightfall, Strike Dragon = % of Exotic Drop and Weekly Heroic for a Legendary engram % - Try to get a Solid team from [b]destinylfg.net [/b] for Trials and go after the 9 win streak for the extra 1% chance. *[b]Tips[/b]* - Try to get the checkpoints you need and transfer them to your other Characters. So you don't need to do them again. - In trials, buy the [b]Favor[/b] and the [b]Boon[/b] before starting a Trials Passage. Then after 4-5 wins by the [b]Mercy[/b]. -Keep a consistent habit to do each and single Raids, Nightfall and etc, every week. Eventually, you will get a taste of OP. Hopefully for you new comers or struggling guardians that are trying to get the Infamous God Weapons, may this help you. Just so you know, i got my 3 Gally's from Nighfall, a Legendary Engram and Raids (Crota). Have a great day! May the luck of Random Number Generator be on your side. *[b]Update[/b]* 30/1/2015 to 13/8/2015 I have edited my post and ROC method was a previous dark below trick. I have now updated to a proper way to get the GOD Weapon. These are the ways i earned mine and consistently. If you do not believe my exp, go check my Character for any further details.
