I know I forget this every few months, so here it is thanks to kevinodie and Jassper who posted this on the official forums:
(Current Level * NextLevel)*500 = XP needed for next level.
So level 1 = 0xp,
(level 1 * Level 2)*500 = (1*2)=2*500= 1000 xp for level 2
(level 2 * Level 3)*500 = (2*3)=6*500= 3000 xp for level 3
If you need to get a rough idea on how much XP a party will get from an average encounter for a certain level, consider the Encounter Calculator v3.5.
It's a great way to figure out how many encounters a party might need. Remember to divide by 10 (assuming your experience slider for the module is set to 10%).
Sometimes I find that I need to reference some minor factiod about the 3.5 ruleset. Here are some links dealing with this.
Before you do anything, save yourself a lot of time and make sure all your modules, areas, object tags, variable names etc. are less than 32 characters. Failure to do so will result in missing data, crashes and other unexpected behavior.
While digging around looking for some ideas, I came across the Writing Your First Adventure article By Wolfgang Baur on the Wizards of the Coast site. It's a fun read and can help stretch your brain:
Kivinen has some great tools for working the the toolset on his site here:
One of the best tools for debuging your module is his check module tool, which can be downloaded here:
Most people have had better luck after patch 1.05, but apparently it is still happening. Here is some basic information to help:
GodBeastX, Ash Darkwood and others recently reported a problem with patch 1.05 where you can no longer set the buy and sell list of item types for stores. Apparently this worked fine in 1.05 beta, but now throws an exception and makes it impossible to set up these lists in 1.05 final.
