Collect resources is the basic things that help you upgrade your castle. In order to progress your castle level, you will need at least one of each type upgraded as high as possible to allow other buildings to progress. There are five resources in this game going in descending order from the top of your resources in the top right of your screen they are: Food, Stone, Timber, Ore, Gold.There is a guide written by , thanks for share.
How to Gather:
Once you tap on the tile it'll give you the option to gather it. You'll come to a screen where you will send troops to the tile. Troops have a carry weight capacity. This stat can be viewed on each troop type in the barracks screen. The siege troop type has the highest capacity out of all types of troops. A tier 3 Fire Trebuchet has a capacity of 15, which means that one Fire Trebuchet can carry 15 of a resource.
Rewards from Gathering:
When the time has elapsed and your troops have returned from the tile you were gathering from the resources you were gathering will be given to you. However, there is a chance that you will also be given a material or materials of many qualities.
Resource Levels and Map:
Every tile has a level. The levels range from 1-5. The higher level the tile, the more a tile will yield before it depletes and the higher grade material it could possibly give. Different level tiles can be found in different parts of the map. This map is available in the bottom left of your screen in-game along with the kingdom map. The map to the right here is what you'll find. Level 1 tiles are on the outskirts of the map. Level 5 tiles are available around the base. As you can imagine, higher level tiles are more valuable than lower level tiles. The easiest place to gather while getting better tiles is the level 3 zone. Many also prefer the zone between 2 and 3 because you get access to both, especially if you're going for Ruins tiles.
The level tile determines how much of the resource is on each tile. Woods and Rocks tiles have the same numbers from level 1-5 but every other tile is different.
Hunt Monster to Gather Resource:
Monster Hunt is an extra which allows you to attack monsters found on the World Map. Different monsters carry up different resources. You have a chance to get rare items and precious resources from them. Therefore, don't waste your energy anymore.
Improving Efficiency:
There are 2 stats that matter when it comes to gathering: Gathering Speed and Army Capacity.
Army Capacity: This stat makes each troop able to carry more resource per person. Army Capacity is a stat that will not matter the more you progress and the bigger your army is unless you really care about sending the least amount of troops possible to a tile.
Gathering Speed: This is the most important stat you can have when it comes to gathering. This stat increases the speed at which you will gather a tile. A tile that would regularly take about 120 minutes (2 hours) to gather would take 60 minutes with a 50% Gathering Speed boost.
How do you get these boots? There are several ways to obtain boosts like this. First, there are talents. For Army Capacity, there are 2 separate talents on the right side of the talent tree: Max Load I and Max Load II. These 2 talents at max can give a maximum of 117% bonus to your troops capacity. For Gathering Speed there are also 2 separate talents on the right side of the talent tree: Gathering I and Gathering II. These at max can give a maximum of 117% bonus to gathering speed. You want to max the second talent of each first. It'll give you the best bonus overall if you can continue to put points into them. I highly suggest maxing gathering speed before max load.
You can also receive Gathering Speed boosts from buying them in both the Gem Shop and the Guild Shop. It’s under the speedup category all the way at the bottom. They are 50% gather speed boosts. These are NOT applicable to Gem Lodes. In my opinion, if you can buy something for guild coins and not use gems, always do that. You can buy a 24-hour one which costs 30,000 guild coins (600 gems). You can also buy a 7 day one for 127,500 guild coins (3,360 gems). In my opinion the 7 day gather speed for guild coins should always be bought if you plan on gathering for a while. It’s a huge help.
Here are the list of best gathering equipment for speed and then add in a couple army capacity pieces you can swap out as needed.
Noceros Mask (Devil Visage)
Lightning Guard (Regal Platemail)
Seafarer Cleats
Electric Lance
Gryphon's Talon
Lastly, there are many researches you can do to increase Army Capacity and Gathering Speed in both the Economy and the Army Leadership sections of your Academy.
If you're curious or looking to see what the max speed boost is: Bryng has found that the maximum you can get is 332% Gather Speed increase.
Tips:
-Troops currently on a tile that are attacked will only be wounded if infirmary space permits.
-Troops behave exactly like attacking a castle when you march to a tile that has someone else on it already. You will lose troops permanently.
-You can ALWAYS recall your troops.
-If you have a shield currently on and you send your troops to a tile and someone gets there before you, you will not attack the tile. It will go to the tile and immediately go back to your castle, as you cannot attack with a shield up.
-As soon as a tile is fully finished, another one spawns nearby.
-If you’re in a busy kingdom you may want to gather lower level tiles if you can be on more often.
-Pay attention to your cargo ship! You can put all those resources you've gathered directly into your bag and sometimes even more.
