In this modpack there are many mods such as the mod's main theme Ben10 and the horror theme.

you have to craft the prototype omnitrix with the matierals(is listed in JEI mod which is included in the modpack) after that you have to survive from endless spore infected humans, zombies and there are some bosses aswell. after levelling up your aliens you can craft the completed omnitrix by:

Any omnitrix that lets you turn into aliens
- 1 Ancient Scroll
- 2 Lime Omni Crystals
- 6 Galvan Circuits
- 6 Redstone Dust
- 24 Raw Titanium
- 20 Galvan Scrap
- 20 Netherite Scrap
- 20 Nether Quartz
after this; Use Fourarms and Shift + Right Click with the designated items on a Grindstone to get the powder form of it. Items include: Netherite Scrap, Raw Titanium, Galvan Scrap and Nether Quartz.
- Combine it together in either a 2x2 or 3x3 crafting grid to get Galvan Alloy Blend, doesn't matter in which order or what placement, it's a shapeless crafting recipe.
- Use Heatblast and Right Click the Galvan Alloy Blend in your hand to be turned into Galvan Alloy (Ingot form).
- Use Upgrade to make Advanced Galvan Circuits. Right Click with Redstone in offhand and Galvan Circuit in mainhand (Don't recommend looking at the ground while doing it, it'll place Redstone on the ground as well, which won't duplicate or anything just seems jarring).
- Use 4 Galvan Alloy and 1 Raw Titanium in the middle to craft a Reinforced Galvan Plate (Same recipe shape as normal Galvan Plate).
- Use Greymatter and Right Click with the Completed Core Blueprint, it will tell you what items are missing to be able to craft it (just like his mech blueprints). Once crafted, it will consume the designated items and blueprint and return give you the core.
- Completed Core Blueprint is gotten from the Galvanologist as one of it's last trades, as well as Randomizer Code Tablets. Blueprint costs 1 Ancient Scroll, Randomizer Tablets costs a sum of emeralds.
- Go to a crafting table and place the materials as if you'd make a Prototype Omnitrix (Core in the middle, Reinforced Galvan Plate in a plus shape, Advanced Galvan Circuit in an X shape).
