Day is faster so you are not forced underground to spawn mobs.
It is an option to mine and craft weapons but you should find plenty of enchanted weapons and food in dungeons. Towers and larger dungeons may contain spawners but are intended to be mostly safe with lots of loot.
The battle is in getting to the dungeons and since they spawn upon leveling some aggression is required.
Thanks for the bug info! I forgot a testing command block that set the world to peaceful. I could not find a problem with the signs but I will investigate if it's a MCedit version conflict. Not one beta test report so hopefully I found everything else.
Fight your way through randomly spawning events and dungeons as the world levels up around you. Your goal is to face four Withers and the ultimate Dragon Tower. You could play this as a survival world, but there's really no need to - gear progression is built into the world with lots of random loot. The towers have themed color pallete with random stacked architecture. Not much in the way of lore or story - but still fun way to spice up any randomly generated world by simply dropping in the schematic.
