This calculator helps you estimate the likelihood of obtaining specific items from enemies in Elden Ring, based on their known drop rates and your character's Arcane stat and discovery-boosting items.
The base percentage chance of the enemy dropping the item.
Your character's current Arcane stat.
Bonus from items like Silver Scarab talisman, Rusted Coins, etc. (e.g., 10 for 10%).
Understanding Elden Ring Drop Rates
In Elden Ring, the chance of an enemy dropping a specific item is influenced by several factors, primarily the item's Base Drop Rate and your character's Arcane Stat. Arcane directly increases your character's Discovery, which is a hidden stat that boosts your chances of finding items.
How Arcane Affects Discovery:
Each point of Arcane generally increases Discovery. The exact formula for Discovery scaling with Arcane is complex and can change with patches, but a common understanding is that Arcane provides a significant boost. Additionally, items like the Silver Scarab talisman and consumables like Rusted Coins further enhance your Discovery rating.
The Calculation:
The calculator estimates your final drop rate using an approximation of how Arcane and other Discovery bonuses contribute to the overall chance. The formula generally looks something like:
Final Drop Rate (%) = Base Drop Rate (%) * (1 + (Arcane Bonus + Item Bonus) / 100)
Where:
Base Drop Rate: The inherent chance of the item dropping.
Arcane Bonus: The increase in Discovery attributed to your Arcane stat. This is not a direct 1:1 conversion, but a significant contributing factor. For simplicity, this calculator assumes a general contribution that can be adjusted.
Item Bonus: The percentage increase from equipped talismans and consumables.
By inputting your values, you can get a more precise idea of how many enemies you might need to defeat on average to acquire that coveted piece of gear or crafting material.
Example:
Let's say you are farming the Guardian Garb (Full Bloom) from the Lesser Erdtree Burial Tree Guardians in the Altus Plateau. The base drop rate for this armor piece is approximately 5%. You have an Arcane stat of 40 and are using the Silver Scarab talisman, which provides a 15% Discovery bonus, and you've consumed a Rusted Coin for an additional 10% bonus, for a total of 25% from items. Inputting these values:
Base Item Drop Rate: 5%
Arcane Stat: 40
Discovery Bonus (Items): 25%
The calculator would then estimate your enhanced drop rate, helping you set expectations for your farming session.

// Approximate Discovery bonus from Arcane. This is a simplified model.
// The exact scaling of Arcane to Discovery is complex and subject to change.
// This assumes a rough linear contribution for demonstration purposes.
// A common estimate is ~1.2-2 Discovery per Arcane point, but it's not linear
// across the entire stat range and can be affected by soft caps.
// For this calculator, we'll use a simplified formula that adds a portion
// of the Arcane stat to the base Discovery, then applies the item bonus.
// Example: If Arcane 40 gives ~40-60 discovery points in some models.
// Let's use a multiplier that results in a noticeable increase.
// A more realistic approach might involve looking up Discovery values per Arcane point.
// For this simplified calculator, we'll treat Arcane's contribution as part of the 'bonus' pool.
// A common understanding is that Discovery = Base Discovery + Arcane's contribution + Item Bonuses.
// Discovery stat caps at around 200-220.
// Let's assume a direct link for simplicity: Arcane stat * X = Discovery Gain
// Or even simpler, let's integrate Arcane directly into the bonus percentage calculation as if it were a flat Discovery value.
// This is a simplification. A more accurate calculator would map Arcane to a specific Discovery value.
// Let's re-evaluate the formula:
// Total Discovery = Base Discovery (from character level, ~100 at start) + Arcane's contribution + Item bonuses
// The item bonus is usually a percentage. Arcane's contribution is an absolute value.
// A commonly cited formula: Total Discovery = 100 + (Arcane * X) + Item Bonus % * Base Discovery (or a derived value).
// This gets complicated fast without exact patch data.
// Let's use a more direct, though still simplified, percentage-based approach for the calculator output,
// where Arcane's *effect* is treated as an added percentage boost, in conjunction with item bonuses.
// This makes the input simpler for the user.
// So, total percentage bonus = (Arcane's effective percentage boost) + Item Bonus %
// The "Arcane's effective percentage boost" is the tricky part.
// Some suggest that for every 2 points of Arcane, you gain roughly 1% Discovery.
// So, Arcane Stat 40 might give ~20% Discovery boost.
var arcaneEffectiveBonusPercentage = arcaneStat / 2; // Simplified: 1% boost per 2 Arcane
var totalBonusPercentage = arcaneEffectiveBonusPercentage + discoveryItemsBonus;
// Calculate the final drop rate.
// The formula is: Base Rate * (1 + Total Bonus / 100)
var finalDropRate = baseDropRate * (1 + totalBonusPercentage / 100);
resultDiv.innerHTML = "Your Estimated Drop Rate: " + finalDropRate.toFixed(2) + "%";
