Be sure to look around for secret areas. You don't have to use the search ability to find them (I find it SO annoying to go into search mode). All you have to do to find them is move your cursor over the trigger, but I must admit, I don't exactly put them out in the open.

Using the secret triggers, you can jump past areas in dungeons. There are ways to move quickly to a boss so you don't have to fight through every time. There are also secret areas that are designed for mass battles.

Has anyone found the kobold caves, the spiderkin village, or the insane zombie crypt yet?

Off hand none of them ring a bell with me, but nice to know they are out there. The more liitle extras the better.

Here's a hint for one of them. Look in snow drifts in D4.

The most likely place to look for them is in areas you normally bypass. I have some that are probably passed hundreds of times per day by players without them ever noticing the blue area transition (you have to put your cursor over it to see it).

I know where the insane zombie crypt is

I made areas like the zombie crypt to give people the chance to spawn a lot of monsters at one time. Just be sure you can handle it.

Hmmm.....this has me wanting to revisit some places and spend a few hours looking around. I know a very easy way to get to the Head Night of Ni

Ive been to all 3 very cool! : )

I believe I found the kobold caves... From D1 right?
