Altering Cold Mastery To Break Immunities

[RyanFialcowitz]

How would I go about altering Cold Mastery so that it will break cold immunities?

You need to change the resistance evaluation code in D2Game.dll to not skip immune monsters when it applies pierce.

How would I go about doing that?

i've posted how to do this in CE(for 1.10)

[RyanFialcowitz]

Can it be done in 1.11b?

-Ryan P. Fialcowitz

[Necrolis]

ofc, just look at nefarius' post on damage generation and go to the section that checks resist >= 100

[RyanFialcowitz]

I looked through the post and didn't see the part about the resist checking, my fault I know but perhaps you could post the exact code I would need to change- it would really help me out and I would obviously appreciate it. Many thanks.

If you want to do it without code editing, you could do something with an on-equip aura (like Conviction, the player would get a charm for example) whose effect is based on the level of Cold Mastery.

Code: Select all

[ PIERCE ]
6FC9A5F8  |> 8B43 0C          MOV EAX,[EBX+C]         EAX = ptResTable->Pierce
6FC9A5FB  |. 83F8 FF          CMP EAX,-1
6FC9A5FE  |. 74 1E            JE SHORT D2GAME.6FC9A61E   (Pierce == -1): NO_PIERCE
6FC9A600  |. 83FE 64          CMP ESI,64
6FC9A603  |. 7C 07            JL SHORT D2GAME.6FC9A60C   (resistance < 100): APPLY_PIERCE 

easy as: search damage gen, ctrl+f pierce....

So, I looked for 83FE 64 at offset 6FC9A600 which I can only assume mena s 9A600 as there is no 6FC9A600. . . And it wasn't there so I searched the entire dll and found it at offset 7A5FB- I'm pretty sure this is the right one as it has 7C 07 right after it. I'm assuming the 64 is what I have to change as it's 100 in hexadecimal.

Thank you- which of those lines should I change to get Cold Mastery to break Cold Immunities? Also, I'm having trouble locating the offsets you listed, such as 6FC9A600- this offset doesn't seem to exist as far as i can tell. I usually see offsets like 0x. . . is this different or what? What should I do? Thank you so much for your help.

The prefix "0x..." just means that the number that follows is in hexadecimal notation, the actual number is what follows, just pretend there is a 0x before the numbers in Necrolis' post.

[RyanFialcowitz]

I couldn't find this offset 6FC9A600, I did find 9A600- but the code after it was not what I should be changing. And still no one has told me what to change. . .

Nop out the cmp esi,64 and the jl(this will make pierce affect all resist types >100). You need to subtract the base address of the 1.11b d2game.dll from the above, they're listed in the tutorial nef gave you in the other thread

[RyanFialcowitz]

1.) I can't find in the tutorial where it covers the subtract command- when I use it I'm presented with many options- which should I chose?

2.) Do I subtract before or after I look for the code?

3.) Am I looking for 6FC9A600 & 6FC9A603 or 83FE 64 & 7C 07 or CMP ESI,64 & JL or all of the above?

4.) I can find addresses like 0006FC98 but none as long as the 6FC9A600 when I tried to do the subtration thing- none of them started with 6 but with 7. . . probably did it wrong though.

5.) I searched for the Nop command- but am not clear on how to use it. Should I just highlight CMP ESI,64 & JL and write nop in there place or is that incorrect?

Obviously I'm having a hard time with this and I do deeply appreciate your patience and help.

The very first page of the tutorial lists the base address for d2game, use windows calculator to subtract that from the above addresses(switch it to advanced mode under options and set it to hex), it should be 6FC20000 for the base, then go to the given address in olly and rightclick->disassemble, then rightclick->assemble, and write nop in the box and hit enter, do the same to the jl and then save

[RyanFialcowitz]

1.) Subtracting 6FC20000 from FC9A600 gives a value of FFFFFFFFA007A600 which is nowhere in the dll. Using OllyDbg all the values are like 7C901046, they all start 7C9 then the numbers after change. I did find 7A601 but the code was different then that listed above.

2.) Right clicking does not present the option to disassemble only assemble.
