FlashBoss - The Guide: the rules a game master needs in their head

Fibonacci spaced repetition and boss fights.

The Guide is built for the person running the table. Every card is one thing a game master should know cold rather than stop to look up: what a condition does, which die a check calls for, what a DC of 15 is meant to mean, what a stat block is telling you, what a party can actually do at level 5.

Each card gives you the term, a scene of that rule happening at a table, the definition you are drilled on, the rule as you would say it out loud, and the numbers underneath. The scene is the point — the rule arrives as something you could narrate, not as an index entry.

Study it in English or German — the pack is fully bilingual. Every definition, rule line, note, scene and reference lesson is written in both, and the German uses the established German rules vocabulary — Rüstungsklasse, Trefferpunkte, Rettungswurf — not invented calques.

5E compatible, built from the System Reference Document 5.2.

In this pack:

• 1,185 cards in 61 themed clusters across five tiers

• Every card's definition, rule line, notes and scene in English and German, and every cluster named in both

• Five tiers that each end in something you can do at the table: adjudicate a check; run a fight; run a caster and read a stat block; know what the twelve classes, the nine species and the feats bring; build encounters, hazards and treasure

• 61 reference lessons in both languages, one waiting at the head of every cluster

• The fifteen conditions, the thirteen damage types, the ability and proficiency tables, challenge rating and XP — the numbers you currently flip pages for

• Boss-fight graduation: no cluster is cleared until its definitions are mastered

The full card list and all reference lessons for every FlashBoss pack are available on the website, along with a playable boss-fight demo.
