While generating characters to see if bones ghosts look okay, found an arcanite chain mail and a pair of broken mithril boots of kicking in UT2.

The wiki almost needs a diagram to show how materials are related.

Sad face. I think it might've been an incompatible save file? If you have a saved game, and you create a new character with the same name as the saved character, then IVAN will just load the saved game.
Was it for example, an old character created with 0.50.3 and reloaded with 0.50.4?

Cool sprites! What does the character look like when he wears them?

I concede that it would be good to expand the copper material chain, and to that end, titanium should find its place in there as a high-end technical material, along with Djinn brass as you suggest. It is good to separate the iron alloys out from that material branch.
I noticed the proposed titanium material is quite similar to mithril, but of course, mithril belongs in a separate line of noble materials. It is nice for players to have the option of hardening to a superior material without needing to change material lines.

In light of Erno's teachings, can I suggest the following iron alloy material chain: pig iron -> iron -> steel -> meteoric steel -> wootz steel -> adamant ?

I wonder how frequently you can make a move? I notice when Izzy appears on the level, you pretty much get bombed straight away. It would be cooler if you have to align your chakras to do assymetrical energy fight with NPCs on the level. It doesn't need to be fatal outcome either.

Does J_kahvi have any good research papers or writings about metaphysics relating to his research?

I'm unsure about adding 'Titanium' to the materials. Though I agree there should be a new iron alloy material with an int requirement of around 25. My reasoning is that there is certainly a material distinctly missing from the iron alloys between meteoric steel and adamant, and that it would be unusual for meteoric steel to suddenly harden into a material invulnerable to rust, only to harden again into adamant which can rust again.
In the past, 'damascus steel' was added to some of the variants, and I think this material would be suitably placed between meteoric steel and adamant.
The only snag is 'damascus' refers to a place not above Valpurus, so we might like to describe it with another place name like Irinox, or Bazaria, or somewhere else?
The stats for titanium appear okay for use in an iron alloy type material.

I want to know what the resident blacksmith thinks.

Well, I meant the new humanoid ghosts will actually be the new generic ghosts, which spawn in these random configs, and then a bones ghost will be of a class derived from the new humanoid ghosts. They will only be spawned when the player dies, with information about limbs, hair and eye colour etc recorded and saved, in the way you mentioned.
It needs to be done this way, because the player looks different depending on int, wis and arm strength. The ghost needs to have its own functions for retrieving the bitmap positions of arms and head in the same way as the player character, to better reflect what the player from the bones file looked like.
Ultimately I'd like to do some really complicated stuff by recording armor and weapons and making ghost copies of these using ghost materials. The ghost items disappear when the ghost gets sucked into hell.
Also, if the player was decapitated, then the ghost should carry his head around.

Ha! Classic chaostrom

This is awesome, just do what you feel is right, you have my as well

Edit: cool changes in the attached images by the way
