Allocating 5+ GB is recommended. More resource intensive than the first iteration.

Made the pack for ease of use and installation.

The most useful items being Davinci's boats, shark axes, realmite pickaxes, aether 2 holystone shields, electric furnaces, muskets, aether 1 orange moas and Bibliocraft atlases.

I've excluded mods that bring forms of automatic mining or drills.

Most of the dimensions include dungeons with bosses.

Xp orbs are disabled but as a replacement for the Silk Touch enchantment, ores can be crafted and broken glass remelted. I hated when xp was added in the game.

I haven't found a scuba diving mod that doesn't make swimming overpowered or unnecessarily changes swimming mechanics.
