An encounter viewers can fight

An encounter is a challenge a viewer rolls against. You set the stat it tests, how hard it is, and what it drops on a win.

Define the encounter

The governing stat is added to the die roll. The difficulty class is the number the roll has to reach. A win rolls the encounter loot table.

Encounter: shadow-stalker
governing stat:   Dexterity
difficulty class: 12
die:              d20
loot table:       cavern-finds

With a d20 and a difficulty class of 12, a viewer needs an eleven or better before their Dexterity is added, so a higher stat widens the margin they win by.

Put it in a pool

Exploration draws from a pool of encounters. Add the encounter to a pool, and give one pool the default so plain explore has something to pick.

Exploration pool: the-hollow  (default)
encounter: shadow-stalker   weight: 5
encounter: quiet-glade      weight: 15
