The Shockwave Werebear Druid is primarily played at the start of a new Ladder season, when many are still struggling with poor gear. Druids that offer enemy control and a health boost are then preferred - especially in hardcore mode.

Gear

The following gear contains "Ladder" runewords, but due to their popularity, according to Blizzard, they will be unlocked in Diablo 2 Resurrected for the first time in both single-player and multiplayer modes. The same goes for ladder uniques and horadric cube recipes.

Helm: 2-Socket Helm with Lore Runeword (Location + Sol)
Armor: 2 socket armor with Stealth Runeword (Tal + Eth)
Shield: 3 Socket Shield with Runeword "Oath of Ancestors" (Ral + Place + Vale)
Weapon: 4-socket sword with "Spirit" runeword (Tal + Thul + Ort + Amn)
Gloves, belts, boots: focus on life/resistances/mana/regenerate mana (e.g. through craft items for magicians)
Amulet, rings, spells: focus on life/resistances/mana/regenerate mana, druid skills, faster cast rate and spells in the inventory

This gear represents the minimum you need to play the build effectively. As a frontline tank, the initial goal is to maximize your resistances. Use all item slots to achieve this. Items that grant bonuses to all skills are another important target, as they grant you and your teammates extra life from Oak Sage. Faster cast rate makes it easier to stun opponents, but that shouldn't be a problem later on with a stun duration of 10 seconds or more.

Mercenary

Type: Act 2 Desert Hireling (Defensive) on Nightmare difficulty with Holy Frost Aura
Gear: Helm of the Tal Rasha set, 3 socket (ethereal) armor with the Runeword "Treachery" (Shael + Thul + Lem), 4 socket (ethereal) Polearm with the runeword "Insight" (Ral + Tir + valley + sol)

The Holy Frost Aura version is recommended as it provides a large amount of additional enemy control for the Shockwave Druid. Otherwise, your mercenary is also a tank and a meditation source (regenerate mana faster). The helm of the Tal Rasha set grants the mercenary great survivability.

Shockwave Werebear Druid Build Tips

Always stay on the front lines and stun as many enemies as possible while your team destroys the monsters you previously disabled.
Always keep your Oak Sage and Grizzly summons active to strengthen your team.
This build is not really suitable for solo players, because even with max gear the damage is negligible. But it's one of the best support builds in the game that will make you a party favourite!

When players enter Diablo 2 Resurrected they can build a powerful structure following this guide above. If you want to build faster then you can buy d2r ladder items.
