Keep and drop

Keep dice

kN and khN keep the N highest dice; klN keeps the N lowest. Other dice are marked excluded. With no N, k, kh, and kl default to 1. The km alias normalizes to kl.

N must be a positive integer. Ties use original positions for stable selection. Selection runs after min/max, explosions, rerolls, and unique, and before targets. If a modifier kind appears more than once, the last one wins. Advantage and pool adjustments that create a selection cannot coexist with explicit keep/drop on the same die.

Dropped dice remain in result.dice with included: false and contribution: 0. Use these fields for scoring and animation.
