- Subtract troop upkeep from hourly food production to estimate how long your available food will last.
- Negative food does not kill troops, but you need enough food when you start an action that requires it.
- Instead of keeping food exposed, plan for both the action's cost and the upkeep before you start it.
CONTENTS
You're about to train troops before KvK. Your other resources and speed-ups are ready, but you're short on food. A guildmate sends some; by the time you open the research screen, the amount has dropped again. That's often when a large army's negative food production starts to hurt. Building more farms isn't always the answer. First, work out your hourly deficit. Then decide when you'll need food and what you'll spend it on.
This guide turns an empty food stock from a reason to panic into a planning decision. The figures below are example calculations, not fixed game values. Use the production and upkeep shown in your own castle.
What negative food means—and what it doesn't
If your troops consume more food than you produce, your available food decreases over time. Suppose you produce 150,000 food per hour and your troops consume 210,000. Your net change is −60,000 per hour. With 600,000 food available, it would reach zero in about 10 hours if no food arrives and nothing else changes.
The key distinction: running out of food does not starve your troops to death. But food still matters. If training, research, or healing requires food, you must have the required amount when you start that action. Upkeep continues while you wait, so opening or receiving food too early can leave you short at the moment you need it.
Before a battle, ask two questions: “How long will my available food last?” and “How much food does the action screen require?” The first determines your timing; the second determines your target amount. Check the displayed cost again just before you start rather than guessing.
Calculate your castle's hourly deficit
If you can see your production and consumption values, your net flow is simply hourly production − hourly troop upkeep. If you're measuring the change in your food stock instead, don't gather food, receive a transfer, or spend food during the measurement period. Any of those will distort the result.
Say your available food falls from 300,000 to 260,000 over one hour. If nothing else changed, your net flow is about −40,000 per hour. At that rate, 260,000 food lasts roughly 6.5 hours. Train more troops and upkeep may rise; if a production boost starts or ends, you'll need to calculate again.
In practice, you need three numbers: available food, hourly net change, and the food cost of your next action. Note them during KvK preparation, after a major training session, and whenever production changes. Don't apply a −40,000 figure measured in the morning to a larger army that evening.
Example negative food calculation
| Available food | Hourly net change | Estimated time remaining |
|---|---|---|
| 260,000 | −40,000 | About 6.5 hours |
| 600,000 | −60,000 | About 10 hours |
More farms or better food timing?
A negative food figure can make you want to rebuild your entire production setup. Check the size of the deficit first. If you're short by 60,000 per hour and a proposed change would add only 20,000 food per hour, you'd still be at −40,000 per hour. The change delays depletion; it doesn't eliminate the deficit. Is that delay worth giving up production of another resource?
Choose based on how you play. If you start training or research frequently throughout the day, more food production may make the gaps between actions easier to manage. If you use food only during planned preparation windows, supplying it closer to those times may be more practical. Judge either approach by the same test: can you start your planned actions without delay?
For example, if you plan two training sessions in one day, covering only the first one's cost isn't enough. Upkeep will consume available food before the second. Conversely, if you have no food-consuming action planned today, a negative counter alone doesn't mean you must transfer resources immediately. For the broader stockpile decision, see the bag versus available stock guide. Here, the question is when to make food available for use.
Set a food window for training and research
Don't leave your food requirement at “we'll find some later.” Check the action's cost, choose a start time, and account for upkeep until then. Suppose research requires 300,000 food, your net consumption is 60,000 per hour, and you plan to start in 2 hours. Putting 300,000 into your available stock now won't be enough: about 120,000 will be consumed in those two hours. If conditions stay the same, you'd need at least 420,000 available now. Allowing a little extra for changes is sensible.
The simpler option, when possible, is to make food available close to the start time. Meet the research's other requirements first, supply the missing food, then start it. Follow the same order for training or healing: check the actual on-screen cost, supply the resources, then start the action. Food won't sit available for hours while upkeep eats into it.
If you genuinely lack the resources, RSS resource packages are available on our site. Calculate the cost and start time first, though: an unplanned supply won't solve a negative food flow by itself. If you're deciding between training and healing wounded troops, the troop budget guide can help you set priorities.
Coordinate guild supplies around battle time
During major training preparations, everyone saying “I need food” at once makes it hard to tell who needs how much, and when. As an R4 or R5, keep a short list: the player starting the action, the food shortfall shown on their screen, and their target time. If 3 players each plan to start research, record all three needs separately. Supplying the first player doesn't mean the guild's job is done.
Gathering from resource tiles can be part of the plan. Use !tiles to view the tiles a player is using and !rss to inspect resource tiles. These tools on LordsRally's commands page help you locate resource tiles. You still need to work out when food will reach the castle and how much upkeep will consume in the meantime. If sending troops to a tile creates a battle risk, decide whether gathering there is safe. You can review the tool's scope on the features page.
Make one final check immediately before the action: is the required food still available, are the other resources ready, and is the player who will start it online? Those three checks prevent the right amount of food from sitting unused at the wrong time. For more economy and battle-preparation articles, browse the blog.
Calculate your castle's hourly deficit and the start time of your next action. Use those two details to plan supplies with your guild.
Three checks before starting an action
- Check the food cost displayed for the action.
- Account for estimated upkeep until the planned start time.
- Once the food is ready, start the action without unnecessary delay.
Frequently Asked Questions
Will negative food production kill my troops?
No. Running out of available food does not starve your troops to death. You will, however, need enough food available to start any action that requires it.
How much food should I prepare before training?
Use the cost shown on the training screen. If you'll keep food available ahead of time, add the estimated net consumption between now and the training start.
Will building more farms always eliminate negative food?
No. If the added production is smaller than your hourly upkeep deficit, your stock will still fall—just more slowly. Base the decision on your own production and consumption values.
