Enkidu travels to Uruk and smashes the local hunters' traps.
The people of Uruk rely on these for food. Enkidu can bring an entire city to its knees without setting foot inside it. Once the people are hungry, Gilgamesh will have to come out and fight on Enkidu's home turf.
It's up to Gilgamesh now. Will Gilgamesh come out and fight? Or send out armies to fight him? Or just wait it out, rationing the food in Uruk and see who gives up first? Or find some way to make Enkidu enter the city, Gilgamesh's home turf? Or do something else?
