Requiem of Reuinis Walkthrough Hub

Navigating the demo tower

Requiem of Reuinis divides its playable demo into three regions spanning thirty maps and six boss encounters. Tasia begins in the Cave Entrance, a tutorial-friendly zone where movement, combat, and the Explore-Alchemize-Research loop are introduced floor by floor. Progression is linear at the region level — defeating the Guardian of the Threshold unlocks the Forgotten Ruins, and clearing both Ruin Warden and Ashen Sentinel opens the Deep Sanctum where the Demo Final Guardian awaits. Each region walkthrough on this hub documents every floor, chest, key door, and boss approach with day-efficient routing in mind.

Magic Tower routing is the hidden difficulty of Requiem of Reuinis. Every tile step costs one day, keys open specific doors, and backtracking burns calendar time you need for alchemy and research at camp. The walkthroughs here assume you want to reach bosses prepared rather than wandering blindly. Cross-reference the Route Planning Guide and Route Calculator when you want to optimize day counts, and use the Interactive Map for visual tile layouts across all thirty demo floors.

Region 1: Cave Entrance

The Cave Entrance Walkthrough covers region one — roughly eight to ten maps where Tasia learns controls, collects her first alchemy materials, and confronts the Guardian of the Threshold. Priority pickups include the Rusty Key, Herb Bundle, and Cave Map Fragment. The Rusty Key bypasses the Ruin Bat encounter on the critical path; the Herb Bundle seeds your first alchemy session; the Cave Map Fragment reveals hidden tiles on subsequent runs, saving scouting days forever after.

First-time players should expect twelve to twenty exploration days in the Cave Entrance depending on how many optional Slime Cultist fights they take. Optimal routing reaches the boss in twelve to fifteen days by skipping nonessential combat and using keys proactively. After the Guardian of the Threshold falls, revisit any unexplored branches before transitioning south into the Forgotten Ruins — leftover herb chests and material nodes are cheap power for the harder region ahead.

• Boss: Guardian of the Threshold — first major gate, teaches retreat timing
• Key items: Rusty Key, Herb Bundle, Cave Map Fragment
• Recommended prep: Beginner Guide, Day System Guide, first alchemy session
• Optimal day count: 12–15 exploration days on a routed repeat run

Region 2: Forgotten Ruins

The Forgotten Ruins Walkthrough documents region two — the largest demo zone with branching paths, stronger enemies, and two boss encounters: Ruin Warden and Ashen Sentinel. The Iron Key gates the main descent route, while Research Notes and the Alchemy Catalyst unlock mid-demo power spikes that change how you approach the Stone Golem shortcut and Ashen Knight patrols. Expect twenty-two to twenty-eight exploration days on an optimal path, or thirty-five plus if you fight every enemy without research upgrades.

Forgotten Ruins routing rewards visiting the left branch first for Research Notes, then crossing to the right branch for the Alchemy Catalyst, then descending toward the boss floors. The Stone Golem blocks a critical shortcut — fight it only when ATK research reaches +2 or higher; otherwise use the Iron Key bypass even at a two-day walking penalty. Defeating both bosses here unlocks the Deep Sanctum, where state mechanics and token equipment replace brute-force stat checks as the primary clearing strategy.

• Bosses: Ruin Warden, Ashen Sentinel — back-to-back mid-demo gates
• Key items: Iron Key, Research Notes, Alchemy Catalyst
• Notable enemies: Stone Golem, Ashen Knight — bypass or research before engaging
• Optimal day count: 22–28 exploration days with research shortcuts

Region 3: Deep Sanctum

The Deep Sanctum Walkthrough covers region three — the deepest demo area featuring state mechanics, token equipment, and three consecutive bosses: Sanctum Keeper, Calamity Echo, and Demo Final Guardian. Priority pickups include the Sanctum Key, Golden Triumph Shard, and Calamity Fragment. The Golden Triumph Shard leads to the S-tier Golden Triumph accessory; the Calamity Fragment enables late-demo state burst strategies with Ashen Death and Dream Anchor.

Deep Sanctum floors reward players who understand tokens and states rather than those who simply stack raw ATK. Dream State with Dream Anchor equipped lets Tasia clear adjacent enemies without moving — dramatically reducing day cost on crowded floors. Budget eighteen to twenty exploration days for navigation plus the fixed boss chain, and read the Tokens & States Guide before entering if you have not yet assembled a state-based loadout. The Demo Final Guardian is the demo's ultimate test of routing, research investment, and equipment synergy.

• Bosses: Sanctum Keeper, Calamity Echo, Demo Final Guardian
• Key items: Sanctum Key, Golden Triumph Shard, Calamity Fragment
• Build focus: State Burst with Golden Triumph, Ashen Death, Dream Anchor
• Optimal day count: 18–20 exploration days plus boss chain

How to use these walkthroughs

Each region page lists floors in recommended visit order, not numerical floor order. Follow the sequence on your first clear, then use the floor index to cherry-pick missed chests on repeat pushes. Every walkthrough cross-links to the adjacent regions so you can plan transitions — finish leftover Cave Entrance chests before committing days to Forgotten Ruins, and complete Ruins research unlocks before the Deep Sanctum state gear detours.

Pair these walkthroughs with the Best Demo Builds page when deciding which equipment to prioritize on each floor, and the How to Beat Bosses Guide for phase-specific boss strategies. The demo's three regions, thirty maps, and six bosses contain enough depth for dozens of hours when routed efficiently — these pages exist so you spend that time on interesting decisions rather than lost backtracking.
