How many pulls do you need in Arknights?
Every pull on the Arknights Headhunting banner costs 600 Orundum, so the question "how many pulls?" is really "how many Orundum?". The tables below answer both for every milestone that matters: a comfortable 50%, a safe 90%, the soft pity threshold at pull 50, the hard pity at 99. All figures start from pity 0; the calculator lets you plug in your own counter.
