Doctor, the neural network is online.
Managing Rhodes Island requires precision. Sanity is scarce, LMD is always running out, and the next Limited Banner is just around the corner. You cannot afford to waste resources on inefficient farming stages or unnecessary upgrades.
We built these **Arknights Utilities** to serve as your personal PRTS terminal. Whether you are calculating the exact LMD cost to E2 90 your new Operator or planning your savings for the next 300-pull spark, these tools are designed to optimize your logistics.
Leveling Cost Calculator
Don't go broke. Planning to promote an Operator to Elite 2 (E2)? Calculate the exact amount of LMD and Battle Records (EXP) needed to reach your target level. Prevents the "0 LMD" error screen.
Material & Farming Planner
Sanity efficiency matters. Need 5 D32 Steel? Input your required materials to find the most Sanity-efficient stages to farm. Compare drop rates between story stages and event stages.
Spark & Pity Calculator
Save for the Limited. Aiming for a limited unit like Wis'adel or Texas Alter? Calculate how much Orundum you need to reach 300 pulls and guarantee the spark.
Orundum & Pull Calculator
Convert your stash. Input your current Originium Prime (OP), Orundum, and Headhunting Tickets to see exactly how many pulls you have available right now.
Operator DPS Calculator
Solve the meta. Compare raw damage output. Is Thorns better for this lane, or SilverAsh? Calculate DPS based on skill multipliers, attack intervals, and enemy defense/RES values.
Trust & Stats Calculator
Maximize bonus stats. Trust provides free stats (Atk/Def). Calculate how many runs of 1-7 or Base interactions you need to hit 100% or 200% Trust to unlock Modules and Paradox Simulations.
Logistics Before Combat
Arknights is a tower defense game, but the real battle happens in the menus. The game's economy is tight. Every Sanity potion you waste on an inefficient stage sets your account progress back.
1. The "Spark" System (300 Pulls)
Limited banners in Arknights are unforgiving. While the "pity" starts at 50 pulls, the only way to 100% guarantee a specific limited operator is to "Spark" them at 300 pulls. This requires **180,000 Orundum**.
2. The Cost of E2 Level 90
Many Doctors underestimate the exponential cost of leveling. Taking an operator from Elite 2 Level 1 to Level 90 costs more LMD and EXP than getting them to Elite 2 in the first place. Use the Leveling Cost Calculator to decide if stopping at Level 60 is a smarter economic choice for your current squad.
3. Trust Farming Efficiency
Trust isn't just for lore. It unlocks Operator Modules which are essential for the modern meta. Farming stage 1-7 is the most Sanity-efficient way to gain Trust, but it takes thousands of runs. Our calculator breaks down exactly how long the grind will take.
Frequently Asked Questions
Does the Material Calculator account for Event drop rates?
Standard Story stages have fixed drop rates, but Events (like Il Siracusano or Lone Trail) often have higher efficiency for specific materials like Manganese or Kohl. Our tool highlights when an active event stage is superior to the story stage.
How is DPS calculated for skills with ramp-up time?
Operators like Thorns (Destreza) or Blaze have "infinite duration" skills that take time to warm up. Our DPS Calculator allows you to view "Average DPS" (including warmup) versus "Peak DPS" (once the skill is fully active), helping you choose the right operator for short vs. long maps.
What counts towards the "Spark"?
Only pulls made on the specific Limited Banner count towards the 300 Spark tokens. Free daily pulls given during events do count. Our calculator allows you to input these anticipated free pulls to lower your required Orundum total.
