Herb is one of the three main resources in Last Asylum, alongside Timber and Grain. However, Herbs are generally more scarce than the other two resources.
Herbs are required for upgrading buildings, researching technologies at the Research Lab, and progressing through various parts of the game. As you reach the late game, having insufficient Herb production or limited sources of Herbs can become a major bottleneck in your progression.
In this guide, we’ll discuss some of the best ways to maximize your Herb production and maintain a steady supply.
1. Upgrade Your Herb Gardens
Herb Gardens are one of the most important sources of Herbs in the game, as they provide a steady supply of Herb production every day.
Because Herb is generally harder to obtain than Timber and Grain, you should prioritize upgrading your Herb Gardens before your Wheat Farms and Lumberyards.
You can also pair your Herb Gardens with the “Instant Produce” skill from the Handyman Specialty to claim a large amount of Herbs at once.
Make sure to assign your UR Survivors to your Herb Gardens whenever possible, as they can significantly increase your overall Herb production.
2. Upgrade the Explorer’s Camp
The Explorer’s Camp provides a consistent source of Herbs through its Idle Rewards.
As you complete higher levels of exploration, the amount of resources you receive through Idle Production also increases. This makes progressing through the Explorer’s Camp important for maintaining a reliable supply of Herbs and other resources.
Try to push your exploration level whenever possible to increase your passive resource income.
3. Research Economy Technologies
Researching Herb-related technologies in the Research Lab can significantly increase your overall Herb income.
These technologies can improve things such as:
- Herb production speed
- Gathering speed
- Resource protection from other players
Make sure you prioritize and eventually max out the Herb-related technologies in both the Economy and Prosperous Economy sections of the Research Lab.
These upgrades may seem small individually, but their bonuses add up significantly over time.
4. Use Instant Produce
Instant Produce is a special skill available through the Handyman Specialty.
It allows you to instantly collect up to one day’s worth of production from your resource buildings. Since you can use this skill at least once per day, it can provide a significant boost to your daily Herb income.
For the best results, use Instant Produce after maximizing your Herb production bonuses so that you get the largest possible amount of Herbs from the skill.
5. Take Advantage of Events and Other Rewards
There are many different activities and events in Last Asylum that provide Herb supplies. Make sure you’re taking advantage of these sources rather than relying only on your Herb Gardens.
Resource Gathering
Send your squads to Herb resource tiles to gather Herbs.
Try not to leave your squads idle. Whenever possible, keep your gathering squads working so you’re constantly bringing additional resources back to your city.
Defeating Resource Monsters
Defeating Resource Monsters can reward you with small amounts of different resources, including Herbs.
While the amount from each monster may not seem significant, these rewards can add up over time.
Falcon Quests
Complete your Falcon Quests every day to obtain additional resource rewards, including Herbs.
These are an easy source of resources that you should take advantage of consistently.
Shops
Various shops offer Resource Supplies that can contain Herbs.
Check shops such as the Expedition Shop and Sanctuary Shop regularly and purchase resource supplies whenever they’re available and worthwhile.
Survival Battle
The Survival Battle event provides resource supplies through its Phase Rewards.
Make sure you complete the required objectives regularly so you can claim these rewards and obtain additional Herbs.
Crystal Cluster Valley
Crystal Cluster Valley provides SR and UR Herb Supplies through its milestone rewards.
Make sure you participate in the event and work toward unlocking the available milestones to maximize the amount of Herbs you can obtain.
Alliance Duel
You can obtain additional Herb Supplies by completing Alliance Duel Phase Rewards.
Participating actively in Alliance Duel not only helps your alliance but can also provide valuable resources for your own progression.
Elixir Scramble
Participating in Elixir Scramble with your Alliance can reward you with SR Resource Supplies, which can provide additional Herbs.
Make sure you participate whenever possible to take advantage of these rewards.
Other Events
Don’t overlook the resource rewards available from other events and activities, including:
- Undead Siege
- Cheese Trap
- Kingdom War
These events can provide additional resource supplies and rewards that help supplement your regular Herb production.
Final Tips
Herb can become one of the biggest resource bottlenecks in the late game, so it’s important to build your economy around maintaining a consistent supply.
Your main priorities should be:
- Upgrade your Herb Gardens.
- Assign your best UR Survivors to Herb production.
- Progress through the Explorer’s Camp for higher Idle Rewards.
- Research Herb-related technologies in the Research Lab.
- Use Instant Produce every day.
- Keep your squads gathering Herbs whenever possible.
- Complete events and claim every available Herb Supply.
- Check resource shops regularly.
By combining these methods instead of relying on a single source, you can significantly increase your daily Herb income and reduce the chances of Herbs becoming a bottleneck in your late-game progression.
