This mod right now contains a small amount of stuff but will be expanded with time. Right now there are some things that i think would be a great addition to vanilla minecraft so i made a mod.
With this modpack you can make use of both amethyst and copper with the new copper and amethys tool and armor sets. But with the amethyst sword you can do somthing really cool. In this mod you can make hardned potion bricks that can then be able to make specifily the amethyst sword have diffrent potion effects. Currently there are only 11 potion bricks. You make the bricks in the new breewer block that can make the brick with just the same ingrediens as if you would make a normal potion. And then you fuse the brick with the sword in the Potion effecter that just do that. But a thing i need to mention is that the Potion Breewer need really hot fuel, Only blaze rods, Coal block and lava buckets work there.
Some other things that can be intresting to discover is the new mossy version of some tree log types. And the new LogStripper that can make bark out of logs.
More stuff will be added by time so just you wait. Have fun!!!
