Dice Rolls

Dice Rolls define how a Player rolls for an attribute when they tap it in the app.
They are the rules that turn an attribute's value into a roll result.

This is a distinct concept from the attribute itself:

Concept	What it is	Example
Numeric Attribute	A single number on your character	Strength: 14
Dice Pool	A physical handful of dice, optionally with modifiers	2d6 + d10, or 4d8 + 4
Dice Roll	The rules for how to roll when tapping an attribute	Roll d20 + x (where x is the attribute's value)

---

Default Roll

Currently, a single Default Roll is configured per game and applies to all attributes.

For Numeric Attributes

The default roll defines what dice to roll when tapping any numeric attribute.
The character x represents the attribute's value.

d20 + x — Roll a d20 and add the attribute's value (standard D&D-style roll)

For Dice Pools

The default is to roll the Dice Pool itself.
Here, x represents the Dice Pool to be rolled.

roll(x) — Roll the dice in the pool

Dice Modifiers

Dice Rolls support special modifiers that change how dice are rolled:

Explosive Dice (!)

A die "explodes" when it rolls its maximum — you roll again and add the result.

d20! — explode on max (20)
d20!>15 — explode on any roll over 15

Reroll (r)

Automatically reroll dice that land on a 1.

d20r — reroll 1s
d20r<5 — reroll any result under 5

Keep Highest / Keep Lowest (kh / kl)

Roll extra dice but only keep the best (or worst) results.

4d6kh3 — roll 4d6, keep the highest 3 (common for D&D ability score generation)
5d12kl2 — roll 5d12, keep the lowest 2

Per-attribute Dice Roll customization is planned for a future update.
