To make an Obedience polearm in Diablo 2: Resurrected, you need to collect and add a Hel rune, a Ko rune, a Thul rune, an Eth rune, and a Fal rune to a 5-socket polearm in this order. These five runes are relatively easy to find, but the base will be more difficult to obtain than the runes.
In the early days of the game on Nightmare difficulty you will have D2R Items a chance to find a 5-socket polearm. If you want to farm one more efficiently, then you can do Nightmare or any Hell difficulty Act at the Secret Cow Level or later in the game. In addition, you can also use the Horadric Cube or let Larzuk add slots to common polearms. But it must be a polearm with five sockets, so in the absence of Bardiches or Voulges, you'd better choose Scythe or Poleaxe.
Eth is a very low-level rune, which you can almost certainly obtain during the exploration of the game's normal difficulty. Thul may also appear in normal difficulty. If you can't find it, you can Buy Diablo 2 Resurrected Runes also find it in the early game of Nightmare. In addition, you can also farm it in the Hellforge in normal mode or The Countess in Nightmare or Hell. Hel first started to fall in Act I Nightmare, Ko on Act II Nightmare, and Fal on Act III Nightmare. In addition, you can cultivate Hel in the Hellforge and The Countess under Nightmare or Hell. But Ko and Fal can only be obtained from Hellforge of Nightmare or Hell and The Countess on Hell.
Although it is easier to get an Obedience polearm in Diablo 2: Resurrected, it still requires players to swipe Act and Boss over and over in the game to get the rune they need. If you want to get this weapon faster, you can buy it through MMOWTS, where the selling price is very cheap, and there are other excellent Diablo 2 Resurrected Items to choose from.
