Requiem of Reuinis Alchemy Guide

How alchemy works

Alchemy is the short-term power system in Requiem of Reuinis. While research permanently upgrades Tasia's base stats, alchemy converts gathered materials into consumables and equipment that help the very next exploration push. You access the alchemy menu at camp during retreat days or at alchemy stations placed on specific dungeon floors. Each craft consumes materials from your inventory and one camp day if performed at base.

The demo includes dozens of craftable items across healing potions, offensive bombs, stat-boosting elixirs, and forgeable equipment pieces. Recipes unlock automatically when you pick up their required materials for the first time, so thorough exploration naturally expands your crafting options. The Alchemist Ring accessory improves output efficiency, making it one of the best early accessories for players who alchemize frequently.

Material types and where to find them

Materials fall into three broad categories: herbs and plants found on exploration floors, monster drops from defeated enemies, and rare catalysts from chests or boss rewards. Herb Bundles appear throughout the Cave Entrance and form the backbone of basic healing potions. Alchemy Catalysts in the Forgotten Ruins unlock mid-tier recipes including offensive bombs and DEF elixirs. Deep Sanctum materials like Calamity Fragments feed high-tier crafts needed before the final demo bosses.

Fighting enemies specifically for material drops is rarely efficient. Most players gather materials passively while routing toward keys and chests, fighting only enemies that block necessary paths. Check the Materials Database for a complete drop table, and cross-reference the Walkthrough to see which floors guarantee specific pickups.

• Herbs — common drops from exploration tiles and weak enemies; fuel healing potions
• Monster cores — uncommon drops from mid-tier enemies; used in stat elixirs
• Catalysts — rare finds in chests and boss rewards; unlock advanced recipes
• Key items — non-consumable materials required for specific forge recipes

Essential recipes for the demo

Healing potions are the highest-priority craft throughout the demo. Keep at least two in inventory before any boss attempt and one before entering a floor with unfamiliar enemies. Offensive bombs help burst down high-DEF foes like the Stone Golem in the Forgotten Ruins when your ATK research is still low. DEF elixirs provide a temporary shield boost that stacks with the Guard skill for tough encounters.

Equipment forging through alchemy becomes relevant in the mid-demo when research alone cannot bridge the stat gap to bosses. The Iron Buckler shield and upgraded weapons available through alchemy stations in the Forgotten Ruins let you skip entire research tiers if you have the materials. However, forged gear consumes rare catalysts — weigh the cost against equivalent research nodes in the Research Guide.

Alchemy days versus research days

Each retreat cycle gives a limited number of camp days. Spending all of them on alchemy produces a strong immediate push but leaves Tasia structurally weak for later regions. Spending all on research builds long-term power but leaves you under-prepared for the next boss. The optimal split depends on your current region and how close you are to a boss gate.

In the Cave Entrance, favor a 50/50 split between alchemy and research. In the Forgotten Ruins, shift to 40% alchemy and 60% research as material costs rise and research nodes provide better returns. In the Deep Sanctum, alchemy matters primarily for pre-boss potion stockpiling — most power comes from research and state-based equipment by that point. The Day System Guide explains how to budget camp days across multiple retreat cycles.

Efficiency tips and common mistakes

Craft in batches during retreat days rather than one item at a time. If you need three healing potions, craft all three in a single camp visit to minimize day waste on menu navigation. Equip the Alchemist Ring before crafting sessions — the efficiency bonus applies per item and adds up across a full retreat cycle.

Avoid crafting items you already have in inventory. Potions stack, but forged equipment does not replace equipped gear automatically. Check your inventory before every craft. Do not convert rare catalysts into mid-tier items when late-demo recipes will require those same catalysts — the Deep Sanctum bosses expect you to have saved at least one Alchemy Catalyst for final potion batches.

Pair alchemy planning with route planning: if your next push targets the Forgotten Ruins boss, pre-craft DEF elixirs and bombs using materials gathered on the previous exploration run. Arriving at camp with materials but no crafting plan wastes a retreat day deciding what to make.

Alchemy and the Alchemy Master build

The Alchemy Master build from the Best Demo Builds page leans heavily into this system. It equips the Alchemist Ring and Research Lens, prioritizes alchemy days over combat days, and snowballs stats through potion buffs before pushing into the Deep Sanctum. This approach requires more retreat cycles but reaches boss-ready power with less precise routing.

Even if you do not commit to the full build, borrowing its principle — alchemize aggressively before boss attempts — solves most beginner gear-check failures. Alchemy is the flexible system that adapts to bad RNG on material drops; research is the stable system that rewards consistent play. Use both, but let alchemy patch the gaps research has not filled yet.
