The use of ADOMBOT and ADOM Improved Guidebook helps me a bit to understand the game. It will be licensed by GNU GPL v3 or later version. Now Thomas Biskup doesn't have to make ADOM Deluxe anymore, they can just make a variation of ADOF (Advanced Dungeons of Freedom) and call it ADOM Deluxe and sell that instead. I can have multiple modes, one mode to copy ADOM exactly (or nearly exactly), and another mode with my own changes to it. And then other people can make more modes/modules/variants. However, I likely cannot work on it completely by myself, so after I make the basic things working I might ask other people for help about some things.
Some ideas I have and might put in the variant mode is:
[*]No background corruption (but corruption from traps, attacks, items, etc still works), but allow monsters to gain more experience instead
[*]Summoned or spawned monsters will not carry anything, and gain lower experience for defeating them
[*]Challenge games selectable at character creation
[*]Auto-roller mode
[*]Additional artifacts, rings, potions, corruptions, etc
[*]Blessed auto-cursing items do not auto-curse, but have 5% chance to uncurse when equipped (so if you unequip it and equip it again, it will then auto-curse)
[*]More races, classes, corruptions, artifacts, spells, potions, books, scrolls, rings, armor, quests, etc
[*]Limited number of spells known at once, if you learn another one you have to choose one to delete
[*]A maximum for the number of uses for any spell, depending on class and level
[*]If you are blind or in a dark place, you cannot tell the color of an object or the title of a scroll
[*]Casters of the wrong type and non-casters will not automatically identify a spell learned, until it is cast and has an effect, or if a spellbook containing that spell is identified (even if you didn't learn the spell from a book, then if identify a book containing the same spell, you will know what it is), merchants auto-identify Create Item spell
[*]Different symbol for open doors, not a slash because that is used for missiles, maybe a colon can be used for open doors
[*]Configuration setting for auto-pickup of thrown missiles only
[*]When fully corrupted, you do not lose the game, but can still play, however you are no longer your original race or class and your equipment changes or disintegrates randomly (including artifacts) making it hard to use, you may still lose that corruption if you are able
[*]More dungeon features
[*]Longer CoC (maybe 125 levels instead of 50 levels), name changed to "Main Dungeon"
[*]Some parts of wilderness randomized at beginning of game
[*]Pious feat more powerful
[*]Some feats normally takable only at level 1 are now takable at any time
[*]Some conditions for multiple feats are first level no longer work
[*]Conduct display (like Nethack), with extra points earned if some conducts are not broken
[*]Wishing, and amulets of life saving, cost experience points to use
[/list]
Some possible new spells:
[*]Monster Aggravation
[*]Create Trap
[*]Create Door (random whether it is open, closed, locked, trapped)
[*]Doom Self
[*]Corrupt (can be used on self or on other creatures)
[*]Flip Position (swaps the position of a creature or object (even self) with the one in the position the same distance and opposite direction from center of board)
[*]Full Power (full PP, lose half of HP and 1 Mana)
[/list]
