Farmer

A class dedicated to farming crops and cooking food.
Farmer is Era's most beginner-friendly class. The act of farming crops is similar to vanilla Minecraft but with reduced chances of drops. Leveling up in this class primarily increases how much yield a player gets from harvesting crops and also unlocks new cooking and crafting options along the way. Farmer class XP is earned from a wide range of regular farming actions like punching crops and cooking food, each worth a different amount depending on the action.
General Mechanics
New Foods
A handful of new food and drink items have been added on top of the existing vanilla ones. Vanilla food items themselves are untouched, aside from having level or subclass requirements.
Banana: functions like an Apple but is harvested from Jungle Leaves instead of Oak Leaves.
Coffee Beans: functions like an Apple but is harvested from Mangrove Leaves instead of Oak Leaves. Inedible.
Lemon: functions like an Apple but is harvested from Acacia Leaves instead of Oak Leaves.
Additional Rules
Depending on the biome, crops grow at different speeds or not at all. 
Crops can only grow on irrigated soil (Farmland that touches water).
