Diablo 2: Resurrected Infinity polearm can significantly increase elemental output capability. If you already have elements such as Lightning Mage, Necromancer, Javelin Amazon, Trap Assassin with element output capability, then making Infinity polearm is very necessary.

D2R Infinity polearm Runeword

The Infinity polearm d2r runeword is "BerMalBerIst". To craft an infinite polearm, you need to add a Ber rune, a Mal rune, another Ber rune, and an Ist rune to the 4-socket polearm in order. That means you need two Ber runes.

4-socket polearm

Any normal polearms found on normal difficulty won't get up to four sockets. You need to be on Nightmare or higher or Secret Cow Level to find the 4 Hole Polearm. If it is Diablo 2 Resurrected Ladder season, You may need to collect D2 Resurrected Ladder Items, more challenging

When looking for slotted items, be sure to remove any equipment that increases your chances of finding a magic item. And no matter where you find it, don't try to add sockets to Bardiche. Bardiche cannot have more than three slots.

How to get BerMalBerIst Runes?

Mal and Ist runes can be found in Act 5 on Nightmare difficulty, and then drop in Hellforge or Countess on Hell difficulty.

Two Ber runes can be dropped randomly in Acts III, IV and V of Hell difficulty.

In Diablo 2: Resurrected, the chance of runes dropping is still very high, but if you want to get a specific rune, it is still difficult, it takes a certain amount of time and effort, if you don't have enough time or Don't have the patience to finish it, then you can buy d2r runes from a reliable supplier like RPGStash to quickly achieve the purpose of making an Infinity polearm. If you want to experience the process of battle, I suggest you Buy D2R Ladder Items appropriately to enhance your character to win the battle smoothly.

Remember, when combining BerMalBerIst, be sure to add them in order, otherwise, the rune words won't work.
