I just started playing the Prominence II modpack again and wanted to share some tips.
Find a Village
Villages have a lot of early game resources that you will need. The loot chests will give you enough food and some starting gear to survive the first few days. Having beds to sleep in to pass the night is also good.
They may also have specialty buildings to help progress.
They also have Waystones that are super useful for traveling long distances.
Early Game Resource automation with Copper Pans
Copper Pans are a great way to get passive resources
Copper Pan:The Copper Pan is a unique block that allows the player to passively pan for resources such as clay and iron nuggets. The pan will only work if it is placed in water and on a sand or gravel block. Overtime the pan will sift and release items it finds. The current loot pool includes: Iron Nugget (15%), Gold Nugget (15%), Sand (24%), Emerald (2%), Gravel (12%), Clay Ball (32%). The speed at which the pan finds items is relative to the random tick speed.
(According to the modpack Oxidized)
Here is an example setup of a copper pan farm:

The items spawn and flow towards the center, where it channels to a chest and hopper.
The great thing about this setup, is that is is easily expandable. Just build more layers up
