Season tools and calculators

Each Last War season brings its own maths — when to deposit, how much resistance clears the wall, whether your research finishes in time. Season tools is a hub of small, single-purpose calculators, one per season, that do that arithmetic for you.

The hub

Season tools (in the dashboard sidebar) is a single index of every season calculator Last Command ships. Each card names the season it belongs to and what the tool does; open one and it mounts inside the dashboard so a logged-in member never has to leave the app.

You are not limited to your alliance’s current season here — the hub lists all of them, so you can plan ahead for a season that hasn’t started or check the maths for one that has passed.

// HOW TO PLAY IT

  • Blood Night runs 3× a day at 02:30, 10:30, 18:30 server time, 30 minutes each — it drains power fast, so reserves and timezone coverage both matter.
  • Assign members whose local time lands in each window so no slot goes uncovered while half the alliance is asleep.
  • Times shift with daylight saving on your side, not the server's — this converter already accounts for that from your device's current zone.
The Blood Night time converter — pick your server offset and read every window in your local time.

The five calculators

There is one tool per season, ordered by season number:

  • Recombination charge planner (Season 1, Crimson Plague) — plans Genetic Recombination charges so your virus research finishes before the season ends.
  • Coal & temperature planner (Season 2, Polar Storm) — works out how long your coal stock keeps the base warm, and how much you need to survive the freeze.
  • Curse Resistance checker (Season 3, Golden Kingdom) — shows exactly how much damage you lose when your Curse Resistance falls short of a target, not just whether you clear it.
  • Blood Night time converter (Season 4, Evernight Isle) — turns Blood Night’s three fixed daily server windows into your own local time so nobody sleeps through a slot.
  • Bank deposit planner (Season 5, Wild West) — times your Bank Stronghold deposits so the five-day term matures before the season closes, with no stranded CrystalGold.

// NOTE

Every tool is zero-setup — it reads its own inputs, holds no alliance data, and works the same whether you open it in the dashboard or on the public web.

The Blood Night pre-fill

One tool behaves slightly differently inside the dashboard. The Blood Night time converter pre-fills the server time zone from your alliance’s saved setting, so you convert against the real server rather than picking an offset by hand. If the alliance hasn’t set its server zone yet, the tool shows a nudge pointing at settings.

// TIP

For officers coordinating cover across the whole roster rather than one member’s slots, the Blood Night coverage board buckets every member by how awake they are for each window. The converter here is the individual, self-serve counterpart — also public at lastcmd.com/tools/blood-night.

Public and shareable

Every calculator also lives at a public URL — lastcmd.com/tools/<slug> — that needs no login. The in-app detail page for each tool links straight to its public twin, so you can drop the link in a Discord channel or a recruit chat and anyone can use it. The bodies are identical; the public page is just the same calculator without the dashboard chrome.

Because the server time zone drives the Blood Night conversion, see Time zones for where that setting lives and how member zones layer on top.
