However you acquire a four-socket shield, once you have it, place the correct for runes into it – Tal, Thul, Ort, and Amn – and you have the Spirit Shield, which grants you the following bonuses.

An even better way is to play as a paladin on Nightmare or Hell, where a four-socket paladin shield can drop even in the beginning levels.

Alternatively, you can use one level 26+ Normal Paladin shield and the recipe above to roll for four sockets through the Horadric Cube, or use Larzuk’s quest. You can even get it on Normal difficulty from about the start of Act V, at which point a four-socket D2R shield can start dropping for you.

The other ways to get it involve the Chaos Sanctuary and Act 5 Normal, though these are far less likely to yield a Crystal Sword with exactly four sockets. To get the Diablo 2 Resurrected 4 Socket Shield and make a Spirit Shield as a paladin is a bit less of a nightmare. By far, the most dependable way to get a 4 socket Crystal Sword is on the Normal Secret Cow Level.
