Pearls of Warding are a crucial resource in Diablo 4 Season 3, primarily used to maintain Zoltun's Warding stacks in
Nightmare Vaults, protecting players from traps and unlocking better loot. They are also used to craft Vault Sigils,
which are key to entering Nightmare Vaults. To farm Pearls of Warding, players can participate in Arcane Tremors, which
are seasonal activities that involve defeating constructs and bosses. The Herald of Malphas mini-boss, found in Arcane
Tremors, is a significant source of Pearls of Warding. Players can also find Pearls of Warding in chests after
completing Vaults.
