# Grouped Rolls

Grouped rolls, using curly braces \`{ }\`, allow you to combine multiple separate dice rolls or expressions into a single unit. This is primarily useful when applying modifiers like \`k\` (keep) or \`d\` (drop) across the results of different roll types (e.g., keeping the best result between a d20 roll and a d8 roll).

Within the braces \`{ }\`, there are two main ways to define the items that form the group:

1. **Comma Separation (\`,\`)**: Each item separated by a comma is evaluated independently. The final result of each item becomes a distinct member of the group.

Example: \`{2d6, 1d8}\` creates a group with _two_ members: the result of \`2d6\` and the result of \`1d8\`.

2. **Plus Operator (\`+\`)**: Items separated by a plus sign are summed _before_ forming a single member of the group. This allows you to combine multiple dice rolls into one value within the group context. _Note: Other mathematical operators like \`-\`, \`_\`, \`/\` are not directly used in this way to combine terms into a single group member; they typically form part of a standard mathematical expression which would evaluate to a single member anyway.

Example: \`{2d6 + 1d8}\` creates a group with _one_ member: the summed result of \`2d6\` and \`1d8\`.

This distinction is crucial because modifiers applied _after_ the group (like \`k1\`) operate on the distinct members created by the commas or the single combined member created by the plus signs.

**Examples:**

\`{2d6, 1d8}\` - Demonstrates comma separation: Roll 2d6 and 1d8 as separate items. The group contains two results. Final group value is the sum of members.

_Example:_ Roll 2d6: \`\[4, 2\]\` (Total 6), Roll 1d8: \`\[5\]\` → Group Members: \`\[6, 5\]\`, Final Value: \`6 + 5 = 11\`

\`{2d6 + 1d8}\` - Demonstrates plus combination: Roll 2d6 and 1d8, add them _first_. The group contains one result (the sum). Final group value is that single member's value.

_Example:_ Roll 2d6: \`\[4, 2\]\` (Total 6), Roll 1d8: \`\[5\]\` → Evaluate \`6 + 5 = 11\` → Group Member: \`\[11\]\`, Final Value: \`11\`

\`{2d6, 1d8}k1\` - Modifier on comma-separated group: Roll 2d6 and 1d8 (two members), then keep the highest member. Final group value is the value of the kept member.

_Example:_ Roll 2d6: \`\[4, 2\]\` (Total 6), Roll 1d8: \`\[5\]\` → Group Members: \`\[6, 5\]\` → Keep Highest 1 (\`k1\`): \`\[6\]\` → Final Value: \`6\`

\`{2d20 + 2d8, 3d6}k1\` - Modifier on mixed group: Evaluate \`2d20 + 2d8\` as one item, roll \`3d6\` as another, then keep the higher of those two results.

_Example:_ Evaluate \`2d20 + 2d8\`: \`\[15\] + \[3, 6\]\` = \`24\`. Roll 3d6: \`\[2, 5, 1\]\` (Total 8) → Group Members: \`\[24, 8\]\` → Keep Highest 1: \`\[24\]\` → Final Value: \`24\`

\`{2d6 + 1, 3d6 - 1, 4d6 \* 2}k1\` - Modifier on complex expressions: Evaluate each expression, then keep only the highest result among the three.

_Example:_ Evaluate \`2d6+1\`: \`\[3, 1\]\` (4) → \`4+1=5\`. Evaluate \`3d6-1\`: \`\[5, 6, 2\]\` (13) → \`13-1=12\`. Evaluate \`4d6\*2\`: \`\[4, 4, 1, 3\]\` (12) → \`12\*2=24\`. → Group Members: \`\[5, 12, 24\]\` → Keep Highest 1: \`\[24\]\` → Final Value: \`24\`
