With so many fields out there being horribly mismanaged, I thought I'd post the best ways to manage a pumpkin patch to maximize the opportunities to spawn a jack o' lantern. Stop clearing off the fields and piling the pumpkins off to the side. This actually keeps the spawn rate LOW since the previously spawned pumpkins need to first decay. To get your field to spawn new pumpkins faster, and thus increase the chances of a jack o' lantern spawning, the pumpkins need to be DELETED. The easiest way to accomplish this is to kill animals and stuff their corpses full of unwanted squash. Mmmm! Pumpkin stuffed venison anyone? Repeat this process until your field is clear and then wait for the corpse to decay. Soon your field will begin to spawn new pumpkins, yay! Necromancers are an ideal character type to work the fields as well. Their horde minions will gather up the squash and then vanish once released. More orange goodness will soon be on its way.
