Overview
Grindstones and anvils are environmental interaction stations scattered across Pywel that provide free, temporary stat boosts to your equipped gear. Grindstones sharpen your weapon to increase its attack power, while anvils reinforce your armor to raise its defense. These buffs cost nothing to apply and require no crafting materials, making them one of the easiest ways to gain an edge before a tough encounter.
Unlike permanent upgrades obtained through refinement at a blacksmith, reinforcement bonuses are temporary. They deplete gradually through combat rather than expiring on a timer, so you can apply them well before a fight without worrying about the buff running out while you travel. The reinforcement status is visible when you hover over your equipped gear in the inventory, displayed as a bonus value (such as +Attack or +Defense) next to the item's base stats.
Grindstones: Weapon Reinforcement
A grindstone is a rotating whetstone that Kliff can use to sharpen his currently equipped weapon. Interacting with one triggers the "Reinforce Weapon" prompt. Once activated, the weapon receives a temporary boost to its Attack stat, typically around +5 attack depending on your current progression stage. This damage increase applies to every strike until the reinforcement is fully depleted.
The reinforcement bonus is usage-based, not time-based. Each hit you land in combat consumes a small portion of the buff. Once all charges are spent, the weapon returns to its base attack value. You can reapply the buff at any grindstone at any time, and there is no cooldown or limit on how frequently you can sharpen your weapon.
Grindstones only affect the weapon you have equipped at the time of interaction. If you switch to a different weapon afterward, the new weapon will not carry the reinforcement bonus. Make sure your preferred weapon is equipped before using a grindstone, especially when preparing for a boss fight.
Anvils: Armor Reinforcement
Anvils function similarly to grindstones but target your armor instead of your weapon. When you interact with an anvil and select "Reinforce Armor," the game applies a temporary defense bonus to all of your currently equipped armor pieces simultaneously. The defensive boost can be substantial, often granting around +15 or more total defense spread across your equipped gear.
Like weapon reinforcement, armor reinforcement is consumed through combat. Each time you take a hit from an enemy, the buff depletes slightly. Once the charges are exhausted, your armor returns to its base defense values. Because the anvil reinforces every equipped armor piece at once rather than a single slot, it provides a meaningful survivability increase for encounters where you expect to absorb significant damage.
You can inspect the reinforcement status of each individual armor piece by checking its stats in your inventory. The bonus appears as an additional number alongside the item's base defense. If the reinforcement number has dropped to zero, it is time to visit another anvil before your next major engagement.
How to Use Grindstones and Anvils
Locate the station. Grindstones look like rotating whetstones, while anvils are the classic flat-topped metal blocks. They are not always marked on the map, so keep an eye out for their physical models in camps, settlements, and homesteads. Using your lantern at night can help you spot them in dark areas.
Approach and interact. Walk up to the station and press the interaction button (Square on PlayStation, X on Xbox, or the interact key on PC). A prompt will appear offering "Reinforce Weapon" for grindstones or "Reinforce Armor" for anvils.
Confirm the reinforcement. Select the option and the buff is applied instantly. There is no animation lock or waiting period beyond a brief interaction.
Check your gear. Open your inventory to verify the buff. You will see the reinforcement bonus listed next to your weapon's Attack stat or your armor's Defense stat.
Both stations are completely free to use. There is no silver cost, no material requirement, and no limit on how many times you can interact with the same station. Reinforcement buffs from grindstones and anvils can also be stacked with food buffs from cooking for even greater stat bonuses heading into difficult content.
All Known Grindstone and Anvil Locations
Grindstones and anvils appear throughout the world, though they are concentrated in areas where players are likely to prepare for combat. Below is a breakdown of all confirmed locations organized by region.
Hernand Region
The Hernand region is where you encounter your first grindstones and anvils. Because this area serves as the game's opening zone, there are more reinforcement stations here than in any other part of the map.
Location | Station Type | Notes |
|---|---|---|
Hernand City (near Turnali's Smithy) | Grindstone and Anvil | Located outside Blacksmith Turnali's shop, near Rhett's Equipment Shop. Available from the start of the game. The most accessible pair of reinforcement stations in the early game. |
Anvil | Southeast of Hernand City, near the homestead buildings. One of the earliest anvils you can find while exploring the countryside. | |
Timberturner Wainwright | Grindstone | Southeast of Hernand City, near logging areas and homesteads. A reliable early-game grindstone that is easy to reach while exploring the surrounding farmlands. |
Howling Hill Camp (Greymane Base) | Grindstone and Anvil | Unlocked after upgrading the camp through Greymane dispatch missions (available from Chapter 3 onward). Once fully upgraded, both a grindstone and an anvil spawn permanently inside the camp, making this an ideal home base for reinforcement. |
Grindstone | Found just inside the main entrance of the castle. Convenient for weapon maintenance when visiting the castle for story quests or exploration. | |
Bandit Camps (Hernand Outskirts) | Grindstone and/or Anvil | Many bandit camps and strongholds throughout the Hernand countryside contain one or both station types. After liberating a camp, the stations remain usable. Check each camp you clear for reinforcement opportunities. |
Demeniss Region
As you progress into the Demeniss region during the later chapters of the story, additional reinforcement stations become available. Grindstones and anvils in Demeniss typically appear inside major settlements, often positioned near Equipment Shops or Tailor Shops. Look for the anvil icon on your map when entering new towns in this region.
Location | Station Type | Notes |
|---|---|---|
Demeniss Settlements | Grindstone and Anvil | Found in major towns near Equipment and Tailor shops. Become available after reaching the Demeniss region (region 2). Look for the anvil icon on the map to locate them. |
Liberated Camps and Strongholds | Grindstone and/or Anvil | Similar to the Hernand region, enemy camps and strongholds throughout Demeniss often contain reinforcement stations that become accessible after clearing the enemies. |
Boss Arenas and Other Locations
Some boss arenas and pre-boss areas contain grindstones or anvils placed deliberately by the developers as a preparation opportunity. If you see one near a fog gate or arena entrance, take a moment to sharpen and reinforce before stepping through. Wandering through the open world, you will also occasionally encounter standalone stations at roadside camps, rest stops, and near quest-giving NPCs.
Reinforcement vs. Refinement
Crimson Desert has two separate systems for improving your gear, and it is important to understand the difference between them. Reinforcement (via grindstones and anvils) is temporary and free. Refinement (via blacksmiths) is permanent but costs materials.
Feature | Reinforcement (Grindstone/Anvil) | Refinement (Blacksmith) |
|---|---|---|
Duration | Temporary; depletes through combat | Permanent; stays until further upgraded |
Cost | Free; no materials or silver required | Requires crafting materials (ore, timber, leather, hides) and eventually Abyss Artifacts |
Where | Environmental stations in camps, towns, settlements, and boss arenas | Blacksmiths such as Turnali in Hernand City and at the Howling Hill Camp |
Effect | Adds a temporary +Attack or +Defense bonus on top of base stats | Increases the base Attack, Defense, or Critical Hit stats permanently (up to 10 levels per item) |
How It Depletes | Usage-based; each hit dealt (weapon) or taken (armor) consumes charges | Does not deplete; permanent upgrade |
Best Use | Quick buff before boss fights, stronghold liberations, or tough encounters | Long-term gear progression throughout the game |
Both systems complement each other. You should refine your gear at a blacksmith for permanent stat growth and then reinforce at a grindstone and anvil for an additional temporary edge before any major challenge. Refinement requires completing the optional quest "Turnali's Request" in Hernand to unlock the feature at all blacksmiths.
Unlocking the Howling Hill Camp Stations
The Howling Hill Camp is the Greymane mercenary band's main base of operations and one of the most convenient locations for reinforcement in the entire game. However, the grindstone and anvil do not appear here by default. You need to expand and upgrade the camp through dispatch missions to unlock them.
Dispatch missions become available starting in Chapter 3. As you complete more dispatches and invest in camp expansions through faction quests, the camp grows and new facilities appear. After enough upgrades, both a grindstone and an anvil spawn permanently within the camp grounds. Since Howling Hill Camp also serves as a fast travel point once its Abyss Nexus is activated, this makes it an ideal hub for topping off your reinforcement buffs before heading out to tackle story missions or exploration.
Tips and Strategies
Always Reinforce Before Boss Fights
This is the single most important habit to develop. Every time you are about to face a boss or enter a liberation zone, take a detour to the nearest grindstone and anvil. The temporary attack and defense bonuses can make the difference between a clean victory and a frustrating defeat. Since the buffs are usage-based rather than time-based, you do not lose anything by applying them early.
Combine with Food Buffs
Reinforcement bonuses stack with consumable buffs from cooked meals. Before a particularly difficult encounter, sharpen your weapon at a grindstone, reinforce your armor at an anvil, and eat a stat-boosting meal. This triple-buff approach maximizes your damage output and survivability without spending any silver.
Mark Stations on Your Map
Grindstones and anvils are not always indicated by map icons, especially those found in smaller camps and homesteads. When you discover one in the wild, place a custom map marker on it so you can return easily before your next big fight. This is particularly useful in the Hernand countryside, where stations are spread across a large area.
Prioritize the Howling Hill Camp Upgrade
Investing in camp expansions through Greymane dispatch missions pays off quickly. Once the Howling Hill Camp has both a grindstone and an anvil, you have a one-stop reinforcement hub connected to the fast travel network. This saves time you would otherwise spend hunting for stations in the field.
Check Reinforcement Status Regularly
After a long combat session or a series of smaller encounters, open your inventory and inspect your gear. If the reinforcement bonus has dropped to zero on your weapon or armor, plan a stop at the nearest station before your next major engagement. The buff can deplete faster than you expect during prolonged fights.
Use Liberated Camp Stations
Every bandit camp and enemy stronghold you clear is worth checking for reinforcement stations. Many camps contain a grindstone, an anvil, or both. After liberation, these stations remain permanently accessible and serve as convenient pit stops during exploration.
Do Not Confuse Reinforcement with Repair
Some players mix up reinforcement with gear repair. Reinforcement adds a temporary stat bonus on top of your equipment's current values. Repair, on the other hand, is handled through the general equipment maintenance system. If your armor is broken or degraded, reinforcing it at an anvil will not fix the underlying damage. Make sure your gear is in good condition before reinforcing for maximum effectiveness.
Frequently Asked Questions
Does reinforcement cost silver or materials?
No. Using a grindstone or anvil is completely free. There is no silver cost, no material requirement, and no limit on how many times you can use the same station.
How long does the reinforcement buff last?
The buff is usage-based, not time-based. For weapons, each attack you land consumes a small portion of the bonus. For armor, each hit you receive depletes the buff slightly. The reinforcement does not expire while you are traveling or standing idle, so you can safely apply it before a long journey to a boss arena.
Can I carry a grindstone or anvil in my inventory?
No. Grindstones and anvils are fixed world objects that cannot be picked up or placed. You must visit their locations in the world to use them.
Does reinforcement affect all my weapons or just the equipped one?
Grindstones only sharpen your currently equipped weapon. If you switch weapons after reinforcing, the new weapon will not have the buff. Anvils, by contrast, reinforce all currently equipped armor pieces at the same time.
Can I stack multiple reinforcement applications?
Using a grindstone or anvil while you already have an active reinforcement buff will refresh the buff to its full value rather than stacking on top of the existing bonus. There is no penalty for refreshing, so feel free to top off your buffs whenever you pass a station.
Do grindstones and anvils respawn or reset?
Grindstones and anvils are permanent fixtures in the world. They do not disappear or break from repeated use. You can return to the same station as many times as you like throughout the entire game.
