That is why you see almost none of these.
Yelinak only drops 1 item from his loot table (excluding head and talisman) every kill. It is very bugged. He should be dropping 3-4 items from his loot table every kill.
Across 13 months, 1 spawn a week, 56~ spawns means 112-168 Yelinak items failed to drop that should've dropped if we had classic drop rates from the beginning.
3 or 4 do exist on the server but they're stupidly rare due to the above.
