Need to add the following to the list because I missed them:

ALTER_NMAGIC_DAMAGE_MAX // Increases the maximum damage that direct damage nature magic spells do. Does not work in original DS.
ALTER_CMAGIC_DAMAGE_MIN // Increases the minimum damage that direct damage combat magic spells do. Does not work in original DS.
ALTER_CMAGIC_DAMAGE_MAX // Increases the maximum damage that direct damage combat magic spells do. Does not work in original DS.
ALTER_GOLD_VALUE // directly alters the gold value of an item. Never used or have seen used, so testing needed to know if it's automatically multiplicative or is a flat value.
ALTER_REQUIREMENTS // Unused.... altering requirements, according to notes in Components.gas, is as supposed to be like this (untested/unconfirmed):

alteration = ALTER_LIFE;
value = 0;
description = "Reduces the Strength requirement of this item by 2.";
duration = #infinite;
is_permanent = true;
is_single_instance = false;
equip_requirements = strength:-2;

Interesting. For what are those alterations used? Is this for modding purposes or a kind of cheat system?

SeriousToni, These items are used for making custom items such as armor and weapons, so that not every item is the same; and different levels of the same item can have different properties.

SeriousToni, these alterations are the hard-coded 'bonuses' that can appear on equipment in Dungeon Siege: Legends of Aranna. Example: You find a blue magical item that is a 1-handed sword. It comes with its basic stats, and then it comes with a modifier because it's a magical item. This is a list of alterations that can potentially appear on the item. Some of them are unused by the original pcontent system, but were still coded into the game by GPG. Any of them can be used on an item and it will be valid.

The only 'cheat' system in the game is in single player, but characters from SP can be imported to MP. Typing, for example, +drdeath into the chat system in single player will give you a character with maxed out skills and stats at level 150. These alterations have nothing to do with that, even though you can achieve the same effect by creating an item that has +140 strength, dexterity, intelligence, and +150 melee, ranged, nature magic, and combat magic skills.

Thank you for the explanation guys - now I understand what's this all about finally Laughing out loud

I tested a few things out last night with ALTER_BLOCK_CUSTOM_DAMAGE which I found to be somewhat interesting.

I gave Phrak's a magic and enchantment block and [enchantment_manager] similar to Rock Beasts, and then gave them 50% custom damage block with ALTER_CUSTOM_DAMAGE. I set the custom_damage = fire and then put +8 fire custom damage on the starter knife, and lowered the knife's min and max damage to 1. I had a knife that did 9-9 damage, 8 of which was fire. I also had the additional 2-4 starting melee damage that a character starts out with without a weapon on, so I was doing 11-13 melee damage. I went to melee the Phrak, and I was hitting it for 6~7 damage a hit. This leads me to believe that ALTER_BLOCK_CUSTOM_DAMAGE works exactly as intended and can be used to implement pseudo-elemental resistances, but unfortunately, there doesn't seem to be any way to make magical spells do custom damage since they are either flagged as combat magic damage or nature magic damage.

I've considered making a mod where armor is normalized across enemies based on their power level, and then giving each mob their own unique resistances to Melee, Ranged, Nature, Combat, Piercing, and Custom damage types using the appropriate ALTER_BLOCK_ alterations.
