Arc Calc

Select the building and the target level (not the current one!). The table then shows you for P1–P5 how high your own investment must be to secure the places.

  • Where?
    • Menu → Calculator
  • A→Z / Age→
    • Toggles between alphabetical sorting and ascending by age.
  • Selection Menu
    • For selecting the legendary building.
  • Level
    • The level to be reached (not the current level).
    • ▼ / ▲: Decrease/increase level by 1.
    • Clicking the field opens a modal for direct input.
  • Presets
    • Preset: Opens the preset page where you can manage worlds and LG presets (sort, rename, delete).
    • Next to it, the selection menus for world and LG – always visible.
    • More information here.
  • Total FP
    • The total volume of FP needed to complete the level – regardless of whether from the owner, group members or external donors. The level "costs" this amount in total.
  • Own FP
    • The investment needed by the owner of the legendary building to reach the next level (total minus rewards).
    • ✕ next to the field resets the own FP value to 0.
  • Toggles in the Arc-Calc
    • Place: When one or more places are already selected, all are deselected. When no place is selected, all places are selected.
    • Factor: Resets the factors of the active tier (Copper/Silver/Gold depending on level and prestige setting) to the standard factors from Setup.
    • External: Clears all entries in the input fields for external deposits.
    • Copy: Copies the text from the adjacent field to the clipboard.
    • Style: Selection of different styles for the copy text (ascending/descending, with/without FP, level, factor).
    • P1 to P5: Selects the places that are included in the copy text.
  • Text Fields in the Arc-Calc
    • Factor: The multiplier that should be applied to the respective place (editable).
    • Base: Base reward of the LG place at this level.
    • Costs: Base × Factor. The amount to be announced.
    • Secure: The additional own investment needed to secure the place (amount still to be paid).
    • Own: The total own investment needed to secure the respective place.
    • External: For entering deviating deposits. Enter unrequested FP deposits and wrong deposits here – the calculator automatically assigns them to the correct places.
  • Colored Markers
    • !FP! – Remaining free FP are not enough for the place.
    • Fact! – Factor error, costs must not exceed those of the previous place.
    • Ext>FPT – External sum exceeds total FP.
    • !Secure! – The place allocation will level up the LG.
    • Highlighted base cell – The place is occupied by an external player (can be enabled in Setup under "Mark Externals").
  • In the Support Chat
    • You usually write: Name LG P5 P4 P3 P2 P1 – descending, because it makes deleting places in that order easier. Claiming a place = striking out the entry from the chat.
  • Sweet Spot
    • From mid levels, the first places are partly already secure when the level opens. E.g. for LG Inno at level 53, P1 is already secure from 1.66 onwards. So claim it directly after opening and never unlock in advance – otherwise there's a risk that a sniper levels up the LG beforehand and secures P1 for much less.
  • Prestige System
    • In Setup (Menu → Setup) you can switch between Classic and Prestige.
    • With Prestige, Silver factors apply from level >200 and Gold factors from level >300. In Classic, Copper factors are used throughout.

Settings & local storage: Everything is saved locally on the device (localStorage). If everything is gone after a restart, it's usually due to incognito/private mode or an add-on that clears the cache. You can export a backup of your settings in Setup (more about that).
