Diablo 1 HD Hellfire Mod | Awake

Hi.
I'm new to the forums. I just want to ask you how can I create a mod for diablo 1 hellfire? Or at least diablo 1.
The mod I want to create would have:

1) New character with new graphics

2) A way to "destroy" weapons in order to turn them into stats (stats given would depend on the stats the weapon destroyed had) for the only weapon the character would have. (the new character) / Or a way which allows the player to add weapons to a new "inventory", meant only for weapons, which would improve the stats of the new character.

3) A few new lines for the habitants of tristram and the new character.

4) 4 new skills unique to the new character. (Naturally the skills would need new SFX and graphics)
4.1) The skills should be able to be binded to new keys (QWER or other player's choice)

5) Belt system of diablo 2.

6) A new ending sequence unique to that new character.

Also....the new character would be Tristana from League of Legends.


So, is there a way to create a mod containing all those features? What programs should I download in order to add those features?

There is no program to do that. You should know ASM/HEX editing https://en.wikipedia.org/wiki/Assembly_language

Holy crap this was made in assembly??? Dear god...Goodluck.
