How to Build a Dnd 5e Calculator

// Dice rolling with modifiers
function rollDice(count, sides, modifier = 0) {
  let total = modifier;
  const rolls = [];

  for (let i = 0; i < count; i++) {
    const roll = Math.floor(Math.random() * sides) + 1;
    rolls.push(roll);
    total += roll;
  }

  return { rolls, modifier, total };
}

// Card draw probability
function drawProbability(deckSize, copiesInDeck, drawCount) {
  // Hypergeometric distribution
  const notDrawing = combination(deckSize - copiesInDeck, drawCount) /
                     combination(deckSize, drawCount);
  return 1 - notDrawing;
}

// Stat point optimizer
function optimizeStats(totalPoints, statCaps, priorities) {
  const allocation = {};
  let remaining = totalPoints;

  for (const stat of priorities) {
    const max = Math.min(statCaps[stat], remaining);
    allocation[stat] = max;
    remaining -= max;
  }

  return allocation;
