Tradeskills

There are four different tradeskills in Pendoria, Mining, Farming, Prospecting, and Woodcutting, which generate the resources: Copper, Food, Gems, and Wood. Resources can be sold on the Market to other players and are a tradeskiller's primary source of income.

Making Tradeskills More Effective
There are 3 ways to boost the amount of resources generated per tradeskill action.

Quint Chance
Quint Chance increases your chance to "crit" on your tradeskill action and generate 5 times the resources you normally would. Quints are calculated with your unrounded Resources per Action. (Normally, your Resources per Action is rounded to the nearest whole number.) This means that you can often generate slightly more (or less) than 5x your normal Resources per Action.

On average, each level of Quint (0.1% Quint Chance) will increase your resource gain by 0.4%. This makes it 4x more effective than 1 point of Resource Boost, though this is only true until your Quint Chance becomes insanely expensive.

Upgrading Quint Chance costs Spare Parts. The Scrapyard building in Scraptown can reduce the Spare Parts cost. Upgrades cost 20 Spare Parts at level 0, and increases by 20 per level.

Resource Boost
Resource Boosts simply increase your Resources per Action by a percentage. However, since your Resources per Action is rounded to the nearest whole number, it may not immediately reflect in the amount of resources you are getting.

Upgrading Resource boost costs Spare Parts. The Scrapyard building in Scraptown can reduce the Spare Parts cost. Upgrades cost 10 Spare Parts at level 0, and increases by 10 per level.

Guild Resource Boost
Guilds can build the Trading Post building which offers all guild members 1% Resource Boost per level. This is multiplicative with the personal Resource Boost, so 10% resource boost * 10% guild resource boost = 21% total resource boost (1.1 * 1.1 = 1.21).

Upgrading the Trading Post costs 3,000,000 Gold, 500 Spare Parts, and 20,000 of each Resource at level 0 and increases by 10% for each subsequent level.

Dungeon Resource Boost
The Dungeon's satchel, which provides only 25% of the amount it states while you do not have any Dungeons running, can be upgraded to boost the amount of resources you gain. This is a bad investment until you either run a decent amount of Dungeons or the other options are too expensive.
