The Phrozen Keep

Use a formula similar to this one:
(stat('ulvl'.accr)<11)?1000:0

If your potion adds +%xp for x seconds you also should use a formula for the duration and set the duration to 0 at lvl 11 or higher in order to make the item not consumable.

Have you tried using the OP columns with itemstat #70?

The value 0 in itemratio.txt prevents an item from getting downgraded to the next lower quality. If you enable the white items again by changing the value to something larger than 0, they will drop ofc.

Open Itemratio.txt and change the "magic" column to 0.

Both can be done with code editing, the first part should be quite simple (removing the check for difficulty when creating a game), the second one will probably require more edits. Check code editing forum, there are a few topics about removing nightmare / hell.

This will work for all types of damage. However, converting physical damage to elemental will not work for poison. Non-physical damage on weapon attacks (for example if you have an amulet that adds 10-20 fire damage) will not get converted. Procs and almost all other stuff including slow, openwounds...

So adding srcdmg to elemental spells will let them work like physical skills that have a chance to proc on hit, CB and maybe even Deadly Strike etc?! Okay, that is cool. srcdmg actually does add weapon dmg to a skill or missile. The damage can also be converted to elemental dmg, like lightning dmg ...

Using skill functions to achieve something special (like generating mana) means that you cannot use them for any skills that already have another skill function. Also, some skill functions require a melee hit, this is most likely the case for the one generating mana. You can spawn missiles with any ...

In data/global/excel you can find several txt files that contain tables with data for skills, items, monsters, etc. If you never modded D2 before, this folder will not be present. You should take a look into some starter guides before you start making changes. This topic contains links to some usefu...

You mean Cobra Strike? That is the only Assassin skill that comes to my mind that generates mana, but afaik it is more of charge that grants mana leech to your next finisher... The skill functions for charge up skills used can be used in other skills, too. Sounds complicated... My idea was to have ...

Sure, you can make sounds for every entry in misc.txt, weapons.txt, armor.txt, skills.txt, etc. Simply change the sound columns in these files. For example "dropsound" in misc.txt refers to the sound.txt file entry played when an item is dropped.

1) letting some skills generate Mana instead of costing Mana when they are used (aka “negative Mana cost”) to create some Mana generating skills (like Fire Bolt, Ice Bolt, Magic Arrow, Bash etc.) There is an assassin skill that generates mana, and it's possible to create skills that add x mana per s...

Starting items will always be normal quality. You could create a new item, set "unique" to 1 and then create a unique version of that item. I don't know if this works, but I don't think so. You could ofc code edit the function that creates starting items, try to look in code editing forum probably s...

virtualbox since it's easy to use and supports everything I need. Guest OS is XP since almost all the programs not running that good with wine runs on it and XP was the last Windows version I used.

manahit -> magic resist
spectralhit -> fire/cold/ltng resist
stoneskin -> phys resist

all of them can cause immunities.

chanc to spawn is controlled by cpick and upick columns.
suprunique mods need to be changed by hand.

I'm running it in a VM with Win XP. Much more convenient than Wine, since not all tools will work out of the box. Maybe this has changed with newer Wine versions, but I'm doing it this way since several years.

And yes. you could simply remove all monumod entries that cause res (set chance to 0 so that they do not spawn, and remove them from superuniques.txt) - but this will limit the available monumods to strong, cursed, fast, multishot, aura and teleport. Ghostly champions would also have to be removed.

Sure you can - but increasing by a fixed value is harder than increasing by a percentage since the synergy columns will always apply percentages. But with the right formula it should work, enjoy figuring out the correct formula :D Increasing minion dmg / hp / other stats by fixed amounts is much eas...

I was surprised that the game did not simply crash with an unhandled exception...
All I made was a typo - misspelled the item type...

Simply leave divide at 1024. Use add / multiply to increase item value if you want to do that. The difference between properties.txt and itemstatcost.txt is that properties.txt is used to add modifiers to items in an more conventient way - automagic attributes, rare items, uniques, sets, runes - whi...

You can also us misc.txt to create potions or tokens or something like that to increase experience so that leveling is not needed at all. Almost everything else can be done with items, there is nothing bad in creating a charm with +1 teleport, +2000 life and +1000 mana if you just want to test somet...

Create a new entry in itemstatost.txt (let's call it "chargedboltsyn" which can store at least a value of 100. Then create a new property in properties.txt which is linked to this itemstatcost.txt entry. In skills.txt simply put some calculation with the "chargedboltsyn" stat in the synergy column. ...

You can do that, yes. If a string cannot be found in patchstring.tbl, the game will simply display "An evil force". For runewords you have to make sure that the patchstring.tbl entry exists, otherwise the game will crash. For everything else - regular items, skill names, monsters, uniques, etc, it w...

Exactly, you can change this entry to whatever you want.
You also can add more columns if you need some space for comments in all txt files. Simply add * as the first character, and the column will be treated as a comment.
