MowLib adds Dual Handed Crafting, and most of the dependent mobs use this feature.
Mow Lib gives options for filtering mobs, while its not available by default, both Pedestals and Effect Scrolls mods use this feature.
All the custom in world built machines are crafted from right clicking a base block with a specific item.
Both Positive and Negative effects can change from pack to pack, by checking an effect catalyst, one can see which effect is associated with which color.
