Capristo is right.
Another way is to pray to a god who can teleport you, or use a wand of teleportation (assuming you can)

Did somebody a few posts up not remember me?!

Oh well. I can't look at the guide right now because i'm browsing on a psp, but i'll have a look later.

One more thing, an object does not show its material if it only has 1 possible material.

Most of what you have there can be easily achieved through script editing.

Although you would most likely want to make new graphics for the characters (Ninjas, battle monks, Russian wrestlers...)

And armor should be dependent on rank (an attribute?). Shinobi, daimyo etc?

Oh, and limited weapons too. Like kunai, tanto, shuriken, cudgels?

In the script, there is a "displacement priority" entry, with the player, IIRC being set at 140.

And if you ever find yourself trapped by an ally who refuses to be displaced, simply command them to stop following you (follow me -> off in the command menu).

Script-whoring probably gave it herpes :/

HARDcoded into the game I suppose. Just like how a valpurium longsword is HARDcoded to disappear.

Don't forget the limbs! All together, an Assasin has negative weight. And yet they don't levitate...?

When you're so bored of IVAN 0.50 that you come onto the forums and download LIVAN, IVANT and IVAN 3d.

...and then when you've truly played too much IVAN when you get bored of those and download AtomicIVAN out of desperation.

...AtomicIVAN?
Jks
