Rocket Engineer wrote: Yet another question: is the weight the chance of spawning out of 100? To phrase it differently, does a weight of 25 mean that item will spawn 25 out of 100 times? No, the chance for one item is [weight of item]/[total weight of all possible items].

So, in this case it would be 25/1230 (If I counted correctly).
