This modpack is a combination between the modpacks Super Modded Survival and the Diamond Dimensions [DanTDM].
I was inactive for 3 years and I couldn't get my account back, and for some reason I was able to access it recently.
Install The Super Diamond Survival
Step 1
Installing a modpack using the Technic Launcher is easy. If you don't already have the launcher downloaded, visit our download page to get the latest version.
Step 2
Type in the modpack name (The Super Diamond Survival) or paste the following url into the search box.
Step 3
Finally, click Install at the bottom right of the launcher after you select The Super Diamond Survival from the list on the left. The launcher will handle everything else!
