FF7 Remake Side Quest 21 Walkthrough and Completion Guide

17 August 2026 | 26

Final Fantasy VII Remake offers players a dense world filled with engaging narratives and intricate optional objectives that flesh out life in Midgar. Among these late-game activities, Side Quest 21, officially titled Secret Medicine, stands out as a crucial task during Chapter 14. Completing this request not only builds your relationship with local communities but also rewards you with valuable character progression tools.

Initiating the Doctor's Request

To begin this quest, you must navigate to the Sector 5 Slums and speak with the town doctor located near the community center. He explains that his medical supplies are running critically low due to the increasing turmoil across the sectors. The doctor provides Cloud with a list of three highly specific ingredients needed to concoct a powerful curative formula.

Accepting this mission requires a willingness to explore multiple regions and engage in high-level combat scenarios. Tracking down each component can be done in any order, allowing players to coordinate their travel efficiently. Preparing your party with versatile elemental magic and defensive materia before setting out is highly recommended.

Acquiring the Moogel Mortar and Medicinal Flowers

The first item on the list is the Moogle Mortar, which can be acquired directly from the Moogle Emporium vendor in the Sector 5 children's secret hideout. You will need to spend a handful of Moogle Medals to secure this necessary tool from the young merchant. Players who have actively explored prior chapters should already possess more than enough medals to cover the transaction.

Next, you must travel to the church where Cloud first reunited with Aerith in the northern area of Sector 5. Upon entering the quiet sanctuary, you will notice a patch of glowing flowers growing near the back of the building. Interacting with these unique plants allows Cloud to safely harvest the second required ingredient for the doctor's prescription.

Defeating the Behemoth for the Final Ingredient

The third and final component is the Behemoth Horn, which serves as the primary challenge of this optional adventure. To locate this formidable creature, you must venture deep into the underground laboratory beneath the Sector 7 Slums collapse area. You can seamlessly access this combat zone by speaking with Wymer near the playground to pick up a concurrent hunt mission.

The Type-0 Behemoth is a brutal adversary that features high physical defense and powerful counterattacks that punish reckless playstyles. To succeed in this battle, players should focus their offensive efforts on crippling the beast's upper and lower body parts independently. Utilizing staggered spellcasting while managing your party's health pool will lead to a decisive victory over this mutated threat.

Completing the Quest and Reaping Rewards

Once all three items are secured in your inventory, return to the Sector 5 Slums clinic to present them to the waiting doctor. He expresses immense gratitude for your efforts and immediately mixes the specialized medicine for the local population. This interaction concludes the operational workflow for this major Chapter 14 campaign checkpoint.

Your primary reward for finishing this job is the Telluric Scriptures Vol. XI, an item that grants additional skill points specifically for Aerith. This allows players to optimize their magical casting capabilities ahead of the challenging endgame sequences. Building strong group synergies through these optional tasks significantly simplifies the final confrontations waiting above Midgar.
