Adventurer’s parchment
Create and view
!newchar
Start a guided chat wizard. Reply with !answer <choice> to select a race, subrace, class, and ability scores. Use !cancel to abandon the wizard mid-way.
!bg3
Rolls a random Baldur's Gate 3 style race and class, then lets you assign ability scores under BG3 point-buy rules (base 8, cap 15, 27-point budget) with !answer <STR> <DEX> <CON> <INT> <WIS> <CHA>. Confirm with !answer yes to save it as your character and get a link to its page. Use !cancel to abandon.
!createchar
Immediately create a level 1 character.
!createchar @username
Broadcaster/moderator only: create a level 1 character for someone else, such as for a viewer who can't chat directly.
!char!char @username
Display your current character summary, or view another player’s saved character.
You keep exactly one active character and one saved backup per channel. If you already have an active character, !createchar, !newchar, and !bg3 will warn you and ask you to confirm with !answer yes before overwriting it.
Manage progress
!levelup!levelup +2!levelup -1
Adjust levels from 1 through 20. HP maximum, current HP, and proficiency are recalculated.
!hp +5!hp -3
Adjust current HP within the character’s valid range.
Save and restore
!savechar!loadchar!resetchar
Save a backup, restore the latest backup, or reset your character.
Fate’s dice
!d20!d20 @username!roll!r
Call upon the D20 of Fate. Use !d20 @username to roll for another adventurer.
!roll NdS[+/-M]
Roll a custom dice expression, such as !roll 1d20+5, !roll 2d6, or !roll 4d8-2.
!roll @username [NdS[+/-M]]
Roll on behalf of someone else in chat, such as !roll @friend or !roll @friend 2d6+3. Anyone can do this.
!roll dex!roll strength
Ability saving throw. Uses your saved character's ability modifier, plus proficiency if your class is proficient in that save. Works with abbreviations (str, dex, con, int, wis, cha) or full names.
!roll stealth!roll animal handling
Skill check. Uses your saved character's modifier for that skill's governing ability. Add @username to roll using someone else's saved character, e.g. !roll @friend perception.
!roll <question>?
Consult fate for a yes-or-no verdict, delivered with a random D&D-flavored omen (natural 20s, Augury, a beholder's judgment, the Deck of Many Things, and more). Example: !roll is enya going to die this time?
Baldur's Gate 3
Roll a character (saved)
!bg3
Rolls a random BG3-style race and class, then lets you assign ability scores under BG3 point-buy rules (base 8, cap 15, 27-point budget) with !answer <STR> <DEX> <CON> <INT> <WIS> <CHA>. Confirm with !answer yes to save it as your character and get a link to its page — see Adventurer's parchment for the rest of the character commands.
Roll a character (flavor only)
!bg3roll
Rolls a full BG3-flavored character in one line: race (with subrace where BG3 has one, like High Elf or Lolth-Sworn Drow), class and subclass, background, alignment, a BG3-style 27-point point-buy ability spread weighted toward the class's primary stat, and a one-line origin hook straight off the Nautiloid.
Companion & origin
!bg3companion
Rolls which BG3 companion you're traveling with — their role, a one-line personality blurb, and an iconic line.
!bg3origin
Casts you as one of the six canonical BG3 Origin Characters — or the Dark Urge — for this run, with their signature hook.
Loot & camp
!bg3loot
Rolls a random magic item drop with a BG3-style rarity tier, from Common up through Legendary.
!bg3camp
Rolls a random camp-night vignette featuring one of the companions.
Knowledgebase
!bg3lookup <name>
Searches a hand-curated Baldur's Gate 3 knowledgebase — companions, origins, classes, races, locations, factions, deities, notable villains, and legendary items — and returns a short blurb with a link to bg3.wiki. Examples: !bg3lookup astarion, !bg3lookup moonrise towers.
!bg3lookup <category> <name>
Narrow the search to one category, e.g. !bg3lookup faction zhentarim or !bg3lookup location grymforge. A bare !bg3lookup lists all recognized categories.
!bg3roll, !bg3companion, !bg3origin, !bg3loot, and !bg3camp are flavor rolls only — they print straight to chat and aren't saved, and none of them touch your !createchar/!char sheet. !bg3 is different — it saves a real character (see the parchment section above). !bg3lookup is also different: it's a reference lookup against the static knowledgebase above, not a roll, so the same query always returns the same entry.
Guild archives
Consult the SRD archives by name. Optional +N upcasts a spell or adds an item attack/damage bonus. Incomplete commands (e.g. bare !rules) return usage tips.
Spells, classes & rules
!rules <topic>!rule <topic>
Summarize a rule (up to 3 messages) with a public link. Examples: !rules magic, !rules combat, !rule advantage.
!spell <spell> [+N]
Shows level, school, casting details, range, duration, components, damage dice, damage type, save, area, classes, and higher-level scaling.
!class <class> [+N]
Shows Hit Die, saving throws, and proficiencies.
!feat <feat> [+N]
Shows prerequisites and the feat description.
Equipment and abilities
!item <item> [+N]
Shows weapon damage, type, range, weight, cost, armor class, properties, and modifier.
!ability <ability> [+N]
Shows the ability score, related skills, and description.
Races
!race <race> [+N]
Shows ability bonuses, speed, size, languages, and racial traits.
!subrace <subrace> [+N]
Shows subrace bonuses, parent race, speed, languages, and traits.
Arena, wilds & the company
A moderator or the broadcaster starts and manages the encounter; any adventurer can roll their own initiative once it's started. Duels and hunts are open to any adventurer with a saved character.
!turn start!turn roll!turn add <name> <initiative>!turn show!turn next!turn prev!turn remove <name>!turn end
!turn start opens the roll window; players call !turn roll to roll 1d20 plus their character's DEX modifier for initiative (each player rolls once per encounter). Moderators can still !turn add monsters, NPCs, or manual scores. The tracker stores one encounter per connected channel, sorts combatants from highest to lowest initiative, shows the active combatant with an arrow, and advances the round automatically.
Parties
!party create <name>!party join <name>!party invite @user [name]!party accept [name]!party decline [name]!party list [name]
!party list shows each of your companies with leader and members. An invite only adds someone once they !party accept it — the party name is optional if they only have one pending invite.
!party leave <name>!party disband <name>
Create a party (you become leader and member), invite friends, and list rosters. Party name is optional on invite if you only belong to one party.
Player duels & hunts
!dndduel @user!dndduel classic @user!dndduel accept | decline | attack | status | end!dndduel!dndduel monster!dndduel party <yours> <theirs>!dndduel party classic <yours> <theirs>!dndduel party accept | decline | attack | status | end!dndduel party hunt <party>!dndduel party hunt classic <party>!dndduel party hunt attack | status | end
Auto challenges resolve when accepted. Classic modes use turn-based attack. Solo !dndduel fights a level-scaled monster (auto); !dndduel monster is classic. Party hunts fight a shared monster and award XP on victory. PvP gives no XP. A pending challenge (accept/decline) expires after 5 minutes if unanswered. Any active classic duel — 1v1, party vs. party, or a hunt — auto-forfeits to the non-idle side after 10 minutes of inactivity, so a duel left mid-fight overnight won't block that channel's dueling next stream.
Custom commands & triggers
Broadcasters and moderators can add their own commands and passive keyword auto-responses right from chat — no code required. These share the !dndbot word used for bot settings below, but different subcommands, so nothing collides. list is open to everyone; the rest are mod/broadcaster only.
!dndbot add <name> <response>!dndbot edit <name> <response>!dndbot remove <name>!dndbot cooldown <name> <seconds>!dndbot list
Creates !<name> as a new chat command. Built-in command names can't be used or overridden.
!trigger add <keyword> <response>!trigger remove <keyword>!trigger cooldown <keyword> <seconds>!trigger list
Fires the response automatically whenever <keyword> appears in chat (no ! needed to trigger it) — wrap multi-word keywords in quotes, e.g. !trigger add \"good luck\" May the dice favor you!
Responses can use {user}, {target} (first @mention, commands only), {count} (times used), and {random:a|b|c} to pick one option at random. Each channel has a cap on the number of custom commands/triggers and a default cooldown to prevent spam.
Battle maps
Create & view
!map create <name> [WxH] [template]
Mod/broadcaster only. Makes a new grid map (default 10x8, up to 20x20), starting as all grass — or stamped with a template's terrain if you name one, e.g. !map create tav1 tavern or !map create tav1 14x10 tavern.
!map list!map view <name>
List every map in the channel, or post a link to one — the map page is a live, auto-refreshing visual grid.
!map delete <name>!map remove <name>
Mod/broadcaster only. Deletes the map along with its terrain and every character token on it — this can't be undone.
Templates
!map templates
Lists every ready-made layout you can stamp onto a new map with !map create <name> [WxH] <template>. A template sets its own default size (overridable) and pre-paints walls, doors, hazards, and features — a starting point you can still touch up with !map paint/!map fill afterward.
${renderMapTemplateList()}
Edit the terrain
!map terrains
Lists every terrain type (grass, forest, water, sand, mountain, road, floor, wall, door, trap, lava, void) — some, like water/wall/mountain/lava/void, block tokens from standing there.
!map fill <name> <terrain>
Mod/broadcaster only. Resets the whole grid to one terrain.
!map paint <name> <x> <y> <terrain>
Mod/broadcaster only. Sets a single cell, e.g. !map paint dungeon1 4 2 wall. Coordinates start at (1,1) in the top-left.
Place & move characters
!map addchar <name> [x y]
Puts your saved character on the map, at the coordinates you give or the first free cell otherwise.
!map addchar <name> @user [x y]
Mod/broadcaster only: place someone else's character.
!map move <name> <x> <y>!map move <name> @user <x> <y>
Move a token; the second form (moving someone else) is mod/broadcaster only.
!map removechar <name> [@user]
Take a character off the map.
Map creation, terrain painting, and moving someone else's token are restricted to the broadcaster/moderators, the same as the rest of the guild's shared state; everyone can place and move their own character.

Enable/disable the bot. The broadcaster can disconnect with !dndbot leave; add purge to delete channel data.
!market on!market off!market status
Off by default. Toggles a threadbare open-stall merchant who drops by the channel every so often (interval randomized per channel) with a one-line D&D-flavored sales pitch for some cheap, secondhand good. Purely flavor — no coin, inventory, or character state involved. status is open to everyone; on/off are mod/broadcaster only.
