Gathering

While the producing of enemy graves may (or may not) be your primary vocation, the land of Agon is one both fertile and rich in raw materials. There are many ways to take advantage of the fruits of the land whether for crafting, military advantages or just plain old profit. 

As a general rule, all nodes have a maximum amount of resources that, once depleted, will slowly regenerate. To farm a resource, treat it like an enemy. Equip the proper tool and un-sheath it, then point it at the given node and harvest away. Your character will continue to harvest until you move them or they can harvest no more.

Mining

Pounding on a rock with a pick-axe will yield one of several types of resource depending on the rock you pound. Plain rocks can yield stone or gems. Stone is your primary resource needed for building cities and shiny gems are valuable for crafting purposes. The shinier looking rocks are metal nodes, they will yield iron ore (at least the normal metal nodes will, more advanced nodes will yield rarer ore) and sulfur that is needed when you want to use magic to blow your enemy to smithereens.

Some key locations will be so rich in minerals you can build a mine on them. Such mines will yield much more metal and ore.

Logging

If being a lumberjack is your dream then look to the trees. Almost every tree you see can be harvested for lumber and turned into wood at a wood bench. Wood is a resource that is needed for much of the crafting and building you will see in Agon.

Some locations are fertile enough to grow a grove in. Like mines, groves will grow healthier trees that will yield more and better lumber.

Fishing

In those rare times when you need a break from all the killing and maiming, fishing is a great way to relax. Find a nice sunny spot, take out your fishing pole and enjoy the waves. Of course fish is also a common ingredient in cooking and will yield many foods that will provide you with beneficial buffs. If you really needed an incentive that is.

Herb Gathering

So you spend the better part of the day hacking enemies, burning legions of foes and peppering your unwary victims full of arrows. No reason you can't stop and pick some flowers when nobody is looking. Especially if you enjoy the benefits of the many alchemical potions and elixirs that herbs gathered from the various bushes and shrubberies around Agon will offer the enterprising alchemist.

Clans and safe havens like cities will also allow you to build a farm that will yield more herbs and fruit from your bushes.

Skinning

Some might say it is slightly macabre but the clever adventurer makes use of anything he can take off a fallen enemy, even their skin or flesh! All beasts and monsters in Agon can be skinned. The various...gifts that such a process will yield can be very useful in powerful enchantments, spells, and indeed some other forms of crafting.

With a skinning knife equipped walk up to the grave of a fallen beast and click on it to begin your grizzly task.
