Here is an example on how to create a 30HD Dire Bear in a couple of minutes.

It’s very easy:
1. Select the monster Dire Bear from the monster list and press the “Generate Monster” button.

2. The Dire Bear stats are now displayed. At the top just under CR, you will see a drop down menu “Racial Hit Dice”, here you can select a greater number of Hit die. select 30D8 and then press the “Recalculate” button. Note that 30D8 is a huge Dire Bear so the size category will change.

3. The Stats for a huge 30D8 dire bear are now displayed. The next thing to do is give it some more feats. Scrolling down the page you will see a number of empty feat slots. You can find out what feats do by selecting the feat on the “Feat Help” drop down box, this will give you a description of the feat and any prerequisites it has.
I gave him Awesome Blow, Improved Bull rush, Improved Critical, Iron Will, Power Attack, and Multi attack (using D&D 3.5 generator).
Now press recalculate again and make sure you don’t have any feat warnings.

If you are happy then you can save your creation and print him out:
