Description

The four-d6-drop-lowest convention builds a score by rolling four six-sided dice and retaining the best three.

The four-d6-drop-lowest convention builds a score by rolling four six-sided dice and retaining the best three.^[1]

This tool repeats that convention for a chosen number of scores and exposes every roll so the totals can be checked.

When to use D&D Stat Roller 4d6 Drop Lowest

Use this tool to apply the stated d&d stat roller 4d6 drop lowest operation with an explicit input and unit basis.

How to use D&D Stat Roller 4d6 Drop Lowest and how it works

Establish the text or game convention described above.
Enter seed, statCount and run the tool.
Read result.rolls, result.stats using the output meanings below.
If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.

Input field	Meaning	Value type	Requirement
seed	Nonblank reproducibility seed; at most 256 UTF-16 code units.	string	required; further conditions in the algorithm
statCount	Stat Count. Units, ordering and applicable branch are specified in the algorithm.	number	required; finite; integer from 1 to 16; further conditions in the algorithm

Require integer statCount 1–16. For each score draw four independent integers 1–6 from one advancing source, retain the rolls and sum them minus one minimum; do not reorder the generated scores or select a game edition’s character rules. A nonblank seed of at most 256 characters selects the existing seeded generator unless execution context supplies random. One source advances through the request; supplied samples must be finite in [0,1). These draws are not cryptographically secure.

The default source hashes the seed’s UTF-16 units into an integer state and advances a deterministic arithmetic generator for each sample. A supplied execution-context random source takes precedence and must return finite values in [0,1). The required seed still must be nonblank and at most 256 UTF-16 code units. These draws provide reproducible sampling without cryptographic unpredictability.^[2]

score = sum(four d6) − min(four d6)

Apply the declared units, ordering and branch conditions.

Output field	Meaning	Value type
result	Object containing the declared output fields.	object
result.rolls	One four-die array per generated score, in generation order.	array
result.stats	Aligned totals after dropping one lowest die from each four-die group.	array

Limitations and assumptions

The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.

Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A returned boolean, signed difference or tied result follows the stated convention; an input error instead means the required input contract was not satisfied. Very large inputs or outputs may be rejected by shared resource limits.

Alternative or Complementary methods

For a related operation, use D&D Loot Generator. Fantasy loot can be an ordinary prop that invites a story rather than a combat reward.

For a related operation, use D&D Encounter Table Roller. A role-playing encounter starts with a situation that participants can respond to.
