Roll a hero. Gather your party. Chase quests through hand-crafted 5th Edition worlds — fight tactical combat, roleplay in-character, level up session to session. Your AI Game Master is always ready, solo with AI companions or live with friends. The world adapts to every choice you make.
A LIVING WORLD THAT REACTS
• Every NPC has memory, motive, and tactics — bards remember your insults, merchants haggle, enemies coordinate
• Hand-crafted adventures with proper pacing, mystery, and branching paths — not procedurally generated filler

PLAY IN CHARACTER
• Speak as your hero — flirt, lie, intimidate, bluff your way through
• Whisper to one ally or address the whole party
• The GM answers in-fiction, every time
REAL 5TH EDITION COMBAT
• Full ability scores, classes, spells, conditions — nothing simplified
• Attacks of opportunity, concentration saves, legendary actions, lair effects
• Positioning, reactions, ongoing effects — all tracked, all real
YOUR HERO PERSISTS
• Level up, prep spells, equip loot — your character grows with every quest
• A campaign journal captures every encounter, every NPC met, every choice made
• Pick up exactly where you left off, on any device

Ratings & Reviews
This app has not received enough ratings or reviews to display an overview.
PARTY STATUS, LIVE
Your party panel now shows a teammate's health, conditions, exhaustion, and resurrection penalty in real time, not just your own. No more finding out a teammate went down only when you talk to them.
CLEARER COMBAT
- Party-wide quest boons (like Infernal Vigor or the Amulet of Theron) now show on the party panel.
- See when a hit lands a massive-damage kill, plus a pass/fail badge for the last saving throw.
- Heroic Inspiration can now reroll an ability check, not just attacks and saves.
FRIENDS & PARTY INVITES
- Friends get their own card with portrait and status, and a proper prompt to play together when you have none yet.
- Invite a friend even while they're offline. The invite now waits for them instead of requiring both of you online at once.
- Raised the away timeout from 5 to 10 minutes, so reading narration doesn't bump you back to the dashboard.
FIXED
- A dead character no longer reads "healthy" just because their HP was restored after a party wipe.
- Fixed a doubled species name on the character sheet (e.g. "High Elf Elf").
- The first tap on a limited-use action no longer burns your whole allowance for the day.
- Fixed doubled wording in some slash-command text ("Break the The Deep Dark Pact-Altar").
- Unavailable action cards now look clearly disabled instead of struck through like they're gone for good.
- Closed more crash paths in audio playback.
