Arknights Operator Promotion & Skill Mastery Cost Calculator

Mastering Arknights Progression: Your Ultimate Operator Cost Calculator

In the unforgiving world of Terra, every Lungmen Dollar (LMD) and every Battle Record counts. As a Doctor, managing your resources efficiently is paramount to building a formidable squad capable of tackling the toughest challenges Arknights throws your way. This interactive calculator is designed to be your strategic companion, helping you meticulously plan operator promotions and skill masteries.

Why Resource Planning is Crucial in Arknights

Arknights is renowned for its deep strategic gameplay and, equally, for its demanding resource economy. Promoting an operator from Elite 0 to Elite 2, or mastering their skills, requires significant investments of LMD, Battle Records, and various crafting materials. Without proper planning, you can quickly hit a resource bottleneck, stalling your progress and leaving your favorite operators underpowered when you need them most.

• Avoid Bottlenecks: Know exactly what you need before you start farming, preventing wasted Sanity.
• Optimize Sanity Usage: Farm the most efficient stages for your required materials.
• Prioritize Upgrades: Understand the full cost of an upgrade path to decide which operators to invest in first.
• Prepare for Events: Stockpile resources in advance for new operators or event-specific farming.

How to Use This Operator Cost Calculator

Our calculator is straightforward and designed for quick, accurate estimations. Follow these steps:

1. Current Elite Level: Select your operator's current Elite status (E0, E1, or E2).
2. Target Elite Level: Choose the Elite level you aim to reach.
3. Current Skill Level: Input the current level of the skill you wish to upgrade (from 1 to 7).
4. Target Skill Level: Select your desired skill level, including Masteries (M1, M2, M3).
5. Number of Skills to Master: If your target skill level is M1, M2, or M3, specify how many skills you intend to master to that level. This accounts for operators having multiple skills (e.g., typically 3 skills for most operators, but some have fewer or more unique progressions).
6. Click "Calculate Costs": The calculator will instantly display the total estimated LMD, EXP, and a detailed breakdown of all required materials.

Note: This calculator uses generalized costs for a typical 6-star operator. Actual costs can vary slightly between operators and rarities, but this provides a very close approximation for planning.

Understanding Operator Progression & Resources

Arknights operators progress through several stages, each demanding specific resources:

Elite Promotions (E0 → E1 → E2)

Elite promotions unlock higher stats, new talents, and often new skills. They are typically the most resource-intensive upgrades.

• LMD (Lungmen Dollars): The primary currency for all upgrades.
• Battle Records: Used to level up operators. Comes in various tiers (Tactical Battle Record, Strategic Battle Record, etc.).
• Promotion Materials: Specific items required for each Elite rank, ranging from basic chips to rare, high-tier compounds. These often include:
  • Chips (e.g., Caster Chip, Defender Chip)
  • Tungsten, Manganese, Sugar, Aramid, etc. (in various tiers)
  • Advanced materials like D32 Steel, Optimized Device, Integrated Device, Polymerization Preparation.

Skill Levels (1 → 7)

Increasing skill levels improves their effectiveness (damage, duration, cooldown, etc.). These upgrades primarily consume LMD and Skill Summaries.

• Skill Summaries: Tiered items (Skill Summary - 1, 2, 3) used to level up skills.

Skill Masteries (M1 → M3)

Beyond level 7, skills can be "mastered" for significant boosts. Mastery upgrades are extremely costly, requiring substantial LMD, high-tier Skill Summaries, and very rare materials. This is where most players experience bottlenecks.

• High-Tier Skill Summaries (Skill Summary - 3): Essential for all mastery levels.
• Elite 2 Materials: Mastery often demands the same rare materials used for E2 promotions, making it crucial to farm these continuously.

Tips for Efficient Resource Farming

To keep your resource flow healthy:

• Daily & Weekly Missions: Always complete these for a steady income of LMD, EXP, and Orundum.
• Base Management: Optimize your Rhodes Island base for LMD and EXP production using the Trading Post and Training Room.
• Event Shops: Events are often the most efficient way to acquire rare materials. Prioritize these!
• Annihilation: Farm Annihilation stages weekly for a large Orundum income, which can be converted to Sanity for farming.
• Material Stages (Supply Operations): Target specific material stages on certain days, especially during periods of low Sanity cost.
• Sanity Potions: Use your Sanity potions strategically during events or when you have a clear farming goal.
