Gwenisdal

Gwenisdal is a Minecraft 1.21.1 modpack focused on Cobblemon, Create, exploration, building, automation and magic.
Catch, train and explore with Cobblemon, while Create adds machinery, automation, factories and engineering-focused building. The pack also includes magic and progression through mods such as Ars Nouveau, Botania, Astral Sorcery and Mystical Agriculture.
Whether you want to build automated Create contraptions, explore the world and catch Pokémon, or work through the various magic systems, Gwenisdal combines these different playstyles into one modded Minecraft experience.
There are also power mods such as Mekanism and Immersive Engineering. If you prefer straight-up power infrastructure, including things like solar power and other generators, these mods have you covered.
Want to ride around on dragons? We’ve got that too! Dragon Mounts Remastered lets you find, hatch and ride all manner of dragons.
Got a darker side and looking for some occult fun? Occultism lets you summon demons and perform rituals.
Want to hunt vampires — or even become one yourself? You can do that with Vampirism.
Maybe you just want to be a farmer, but vanilla Minecraft doesn’t have enough crops or food for you. Farmer’s Delight adds more crops, ingredients and food recipes for all you green thumbs out there.
And if building a thriving settlement is more your thing, MineColonies lets you design and build your own colonies with NPCs who work for you.

Some extra details to prevent crashes:

Open Curseforge App click on the modpack and click the 3 dots and click profile options and scroll down till you see Additional Augments and type: -XX:+UseZGC and click Done. Bare in mind this setting does increase RAM usage quite a bit, and REQUIRES AT LEAST 8GB OF VRAM so if your Graphics card only has 4gb dont use this.

Then open curseforge/ click settings in bottom left and click minecraft then scroll to bottom till you see additional augments and paste:
-Dsodium.render.asserts=false -Djava.util.concurrent.ForkJoinPool.common.parallelism=1

When in game if you are able, run the command: Flywheel backend instancing and hit enter 
this stops multi-threading crashes

Create High Seas it will prompt you on load up how to disable the wave visuals. Disable if your PC isnt up to scratch.
if not when game is  loaded you should see a button called mods click that and find high seas and click config then turn waves off.

You will need to change some keybindings notably: Party Summery (Cobblemon Section), Open Backpack (Sophisticated Backpacks) and right at the bottom there is one for Cobblezones. Other keybinds will have to be figured out as we play.

Botania is now included when you download however as its not a Curseforge mod it wont show up in Curseforge but don’t worry it is in your mods folder.

If you want shader you will need to download Iris, however i haven’t tested shaders so just be careful.

Also noticed you will need to make sure any moving Create contraptions use portable storage interfaces to connect to storage blocks as found when Chutes/Funnels try pull from moving contraptions it occansionally throws an error/crash, however i think i may have solved that but to be safe use the poratble storage interfaces.

If anyone notices anything that could be better comment down below.
