I tried to get Jelkhor’s Blast Knive from the rune and wasted about 20 without a single one. Then I’ve read that it’s Majasan Dagger, changed the loot filter to show me all Majasan Daggers and 4 times in a row, whenever I used the rune on a Majasan Dagger, I got Jelkhor’s Knive.
Is this a known fact? Because I never read this anywhere and all are just saying “use the run until you get item X”. This makes target crafting much easier if it wasn’t some almost unreal RNG luck.
