The landscape for acquiring Sundering Charms in Diablo II: Resurrected has shifted significantly with the release of the “Reign of the Warlock” expansion. Previously a relatively consistent drop, these charms – crucial for overcoming monster immunities – are now considerably more difficult to obtain, with a new system heavily influencing drop rates based on Terror Zone tier and Herald level.
The core change revolves around the introduction of “Latent Sunder Charms,” which exclusively drop from Heralds, special monsters that appear within Terror Zones. This represents a departure from the previous system where Sundering Charms could drop from a wider range of monsters. The new system introduces a complex drop table governed by a series of weighted probabilities and conditional checks, making the acquisition of specific Sundering Charms a more involved process.
How the Herald Drop System Works
The drop mechanics are determined by a series of “Picks” within a data file, dictating the order in which items are considered for drop. A negative Pick value indicates that items are selected in a predetermined sequence. Heralds can drop several categories of items, including standard equipment, charms, Terrorize Act Consumables (Worldstones) and potions. The probability of a Sundering Charm dropping is tied to a specific entry within this table.
The system prioritizes several item categories: “Herald Item,” “Herald Item – 1 Extra,” “Herald Item – 2 Extra,” Sundering Charms, Terrorize Act Consumables, and potions. The “Herald Item” categories encompass equipment, jewelry, charms, gems, and runes. Crucially, the Sundering Charm category has a significant “no drop” rate, meaning it’s not always considered for a drop even when a Herald is defeated.
The number of items dropped is limited to six. If the preceding items fill all six slots, the final potion category may not drop. However, the potion category itself has a maximum of four potential drops, adding another layer of randomness.
Tier-Based Restrictions and Charm Availability
A key element of the new system is the restriction of Sundering Charm drops based on the Herald’s tier. Heralds are categorized into five tiers: Tier 1 (Dreadful Herald), Tier 2 (Wretched Herald), Tier 3 (Fearful Herald), Tier 4 (Horrific Herald), and Tier 5 (Terrifying Herald), with higher tiers appearing after defeating lower tiers. Sundering Charms are not guaranteed to drop from Heralds of Tier 3 or lower. The drop table includes a conditional statement – “cond(‘MonsterTestElite’, herald)*(stat(‘heraldtier’.accr) >. 3)” – which means Sundering Charms are only selectable from Tier 4 and Tier 5 Heralds.
However, even from lower-tier Heralds, there’s a small chance for a Sundering Charm to drop if a unique Grand Charm is rolled, and that Grand Charm then has a chance to become a Sundering Charm. This occurs with a probability of 12/13 for a Sundering Charm and 1/13 for a Gidbinnon’s Calling. This chance is influenced by the player’s Magic Find (MF) stat.
The Impact of Herald Item Extras
The “Herald Item – 1 Extra” and “Herald Item – 2 Extra” categories further complicate the drop rates. “Herald Item – 1 Extra” is only available from Tier 2 and Tier 3 Heralds, while “Herald Item – 2 Extra” is available from Tier 4 and Tier 5 Heralds. However, “Herald Item – 2 Extra” has a negative Pick value of -2, meaning it selects two additional items from the equipment, jewelry, charms, gems, and runes categories. This effectively increases the competition for drops, potentially reducing the chance of a Sundering Charm appearing.
Multiplayer Considerations
Playing in Terror Zones with multiple players (a “multiplayer bonus”) does influence the drop rates of Sundering Charms and Terrorize Act Consumables, as these items have a “no drop” component. The multiplayer bonus reduces the effect of this “no drop” condition. However, other items in the drop table do not have a “no drop” component and are therefore unaffected by the multiplayer bonus.
Understanding the Drop Probabilities
Calculating the precise probability of a Sundering Charm dropping is complex, but the data suggests a low overall chance. The probability of a unique Grand Charm dropping from a Herald, and then rolling as a Sundering Charm, is approximately 0.29% for Tier 1 Heralds, increasing to 0.58% for Tier 2/3 Heralds and 1.16% for Tier 4/5 Heralds. However, these calculations only account for the chance of a unique Grand Charm rolling as a Sundering Charm; the base chance of a unique Grand Charm dropping in the first place must also be considered.
The system is designed to encourage players to progress through higher Terror Zone tiers to increase their chances of finding Sundering Charms. However, the low drop rates and tier restrictions mean that acquiring these charms remains a significant challenge, even with a dedicated farming strategy.
