DIGITAL DM SCREEN & HOUSE RULES
Reliquary
The rules reference you actually reach for: conditions, actions, the tables you look up mid-session. Plus the house rules your table has accumulated and the custom systems you invented.
THE FIFTEEN UNWRITTEN RULES
Every table has house rules. Almost no table has them written down.
Potions as a bonus action. Flanking, but only sometimes. Nat 20 on a skill check doessomething. Crits max the first die. You know all of these; your players mostly know them; and roughly once a month there's a two-minute conversation about whether one of them is a real rule or something someone remembered from a podcast.
The cost isn't the two minutes. It's that unwritten rules get applied inconsistently, which is the one thing that genuinely undermines a table's trust in a DM. Not being wrong, but being differently wrong on different Fridays.
Reliquary is where all of it goes: the screen you reach for, the rules you look up, the amendments your table has accumulated, and the systems you invented that aren't in any book.
Six tabs, one job
The screen
The tables you look up mid-session, on the side of the table where you need them.
Compendium
The rules themselves, searchable, for the ones you genuinely can't remember.
House rules
Your table's accumulated amendments, written down, where a player can be shown them.
Custom systems
The subsystem you invented (reputation, corruption, ship combat) as a first-class thing.
Trackers
Counters for the resources you always forget: legendary resistances, lair charges, the doom clock.
Player-visible
Your players get a Reliquary tab too, so the house rules aren't a thing only you can quote.
THE TRACKERS
Nothing on the table reminds you the dragon has three legendary resistances.
Some resources announce themselves. Hit points go down where you can see them. Spell slots are on a sheet. But the ones behind your screen (legendary resistances, lair charges, the number of times the villain has escaped, the clock you're running on the ritual) exist only in your memory, mid-fight, while five people talk.
So they get forgotten, and a boss burns a resistance it had already spent, or the doom clock never quite runs out. The trackers are counters for exactly those: the things that are only real if something is holding them for you.
Questions a DM would actually ask
What's actually on the DM screen?
The reference you reach for during play rather than the whole rulebook: conditions, actions, the common tables. The value of a DM screen was never comprehensiveness; it was that the eight things you look up constantly are in one place.
Why do house rules need a home?
Because every table has fifteen of them and none are written down. Which means they get applied inconsistently, forgotten across a hiatus, and argued about at exactly the wrong moment. Writing them somewhere your players can also read is most of the fix.
What counts as a custom system?
The subsystem you invented for your campaign: a reputation track, a corruption meter, ship-to-ship combat, a heist clock. Things that aren't in any book, that your table treats as real rules, and that currently live in your head.
What are the trackers for?
The resources with no natural home. A dragon's three legendary resistances. How many times the lair has acted. A countdown you're running behind the screen. They're the things most often forgotten, because nothing on the table reminds you they exist.
Do my players get access?
They get a Reliquary tab in their portal. This matters more than it sounds: a house rule everyone can read is a house rule nobody argues about, and "is that a real rule?" stops being a question you have to adjudicate.
Is this campaign-specific?
Reliquary sits in the Reference group rather than inside a single campaign, so the rules and systems you've built follow you. House rules that took three years to settle shouldn't have to be reinvented for the next game.
Write down the fifteen rules your table already plays by.
Then let your players read them, and never adjudicate "is that a real rule?" again.
