How Does Laplace Help With Team Building and 3T Farming in Fate/Grand Order?

Updated

Laplace is the battle simulator component of Chaldea, a cross-platform tool for Fate/Grand Order. According to the site's own description, it is "a novel battle simulator to help building your team, help 3T farming." In practice, that means you use it to test team compositions and farming loops in simulation before committing real AP, materials, or grails in the game. It is most useful if you already have a rough idea of the servants you want to use and need to check whether a specific 3-turn (3T) farming setup actually works.

What Laplace Is and Where It Fits

Chaldea is described as being composed of two parts:

Component Role
Chaldeas A planner for materials, servants, events, and similar long-term planning
Laplace A battle simulator for building teams and working out 3T farming

So Laplace is not a general planner. Its scope is combat: given a team and a battle, it simulates what happens. That makes it complementary to Chaldeas — you plan what to build in Chaldeas, then test how it performs in Laplace.

What Team Building With a Simulator Actually Solves

Building a team in FGO usually involves several interacting constraints: NP charge, card distribution, skill cooldowns, class advantage, and enemy HP thresholds. A simulator lets you vary these without spending resources.

Typical questions Laplace is suited to:

  • Does this team reach enough NP gauge to fire the needed Noble Phantasms on turns 1–3?
  • Which servant order (front line vs. back line, plugsuit swaps) makes the loop consistent?
  • Does the damage output clear the wave's HP, or does it fall short?
  • What happens if a card draw or an RNG-dependent effect goes badly?

Because it is a simulation, you can iterate on these quickly rather than discovering a failure mid-farm.

How It Relates to 3T Farming

3T farming means clearing a node in three turns, usually by firing AoE Noble Phantasms each turn. The hard part is rarely raw damage — it is the resource chain: starting NP, charge skills, and refund or battery effects that must line up across exactly three turns.

Laplace is aimed at exactly this: "help 3T farming." You set up the team and the battle, run the simulation, and observe whether the three-turn loop holds. If it does not, you adjust the composition or the skill order and run it again.

Getting Started

The site notes that JavaScript must be enabled to run the app, and it points to a document site for further reference. The practical starting sequence is:

  1. Enable JavaScript in your browser.
  2. Open chaldea.center and let the app load.
  3. Use the Laplace side of the tool to define a team and a battle scenario.
  4. Run the simulation and read the turn-by-turn result.
  5. Adjust the team or skill order and re-run until the loop is stable.

Common Friction Points

  • JavaScript required. Without it, the app will not run at all.
  • Simulation is not the game. A simulated result reflects the model's assumptions; verify anything critical in-game before relying on it for a long farming session.
  • Setup effort. A simulator rewards accurate input — servant levels, skill levels, and CE choices all affect the outcome, so a rough setup gives rough answers.

When to Use Laplace vs. Chaldeas

  • Use Chaldeas when the question is "what do I need to farm or build?"
  • Use Laplace when the question is "will this specific team clear this specific battle in three turns?"

If your goal is a reliable 3T farming loop, Laplace is the part of Chaldea designed for that job.
