We can't find any source for this item (quests reward, drop, etc). It's highly probable this item is not obtainable right now.
Would be so much better if it had any other perk other than Splinter Shot... lol
why range weapon and spear cant replace with fire gem ? just lightning and void only can put in slot gem.
@R3DneckSuperman fully leveled splintershot, corruped bain, and an amber gem (nature weakness) would probably annihilate bosses in invasions. getting the split distance right wouldn't be too hard when they're standing at the door
