If a player wants to make an Infinity polearm in Diablo 2: Resurrected, the player needs to add a Ber rune, a Mal rune, another Ber rune, and an Ist rune to the 4-socket pole in that order. Because the infinite rune in this game is "BerMalBerIst". It's worth noting that players must add them in exactly that order. Otherwise, Runewords will not work.
On Normal difficulty, players cannot find a 4-hole polearm anywhere. Any normal polearms found on Normal difficulty will not gain up to four sockets if the player adds them using Horadric Cubes or Razuks. Players will need to play on Nightmare or higher or Secret Cow Level to find the 4 Hole Polearm.
When looking for slotted items, be sure to remove any equipment that increases your chances of finding a magic item. And no matter where the Diablo 2 Resurrected Runes player finds it, don't try to add the socket to Bardiche. Bardiche cannot have more than three slots. All of the runes in this recipe are hard to find, and it requires two Ber runes, making it a particularly difficult rune word to complete.
The Mal and Ist runes can be found in Act 5 on Nightmare difficulty, and later drop in Hellforge or Countess on Hell difficulty. The Forge of Hell or The Countess does not drop Ber runes on any difficulty, so players need to be lucky enough to drop two random Ber runes in Acts III, IV, and V of Hell difficulty.
Infinity is primarily used by players who rely on elemental damage, which allows their mercenaries to benefit from the Aura of Faith. It is also sometimes used directly by Lightning Sorceresses, as reducing the enemy's Lightning Resistance does not Buy D2 Resurrected Runes apply if the mercenary is equipped with infinity. If the player wants to successfully craft the Infinity polearm but cannot find all the runes, then the player can go to MMOWTS for help. They offer a large selection of Diablo 2 Resurrected Runes with cheap prices and fast delivery.
