About this project
What does Sig's Flint Age add?

Overview
This is a mod designed to change the early-game progression of Minecraft. It does this with the addition of flint-age tools, which allows for a different progression to iron than the standard wood-to-stone tools. It takes inspiration from similar mods that change progression, trying to blend different features from each of them.
Features
- Tree punching has been disabled and is punished with the player taking damage.
- A Flint tool tier.
- Flint can be knapped on stone for flint shards.
- A Flint Knife can be used to gather plant fiber from grass and sticks from leaves.
- Plant String can be used for tools and to make a Sieve.
- The Sieve is used as a more efficient way of getting flint from gravel.
- A mortar and pestle have been added to get copper, tin, and bronze powder.
- Ore powders can be used on a campfire to get ingots.
- Campfires no longer start with fire when placed.
- A flint rod has been added as a single-use flint and steel.
- A bronze tool tier and armor set have been added, replacing the stone tier.
- Stone and Wooden tools functionality has been disabled but can still be crafted to support mods which require them.
Creators notes
This mod is still a work in progress and thus subject to change. Suggestions and criticisms are encouraged and much appreciated.
Technical Stuff
This mod utilizes Tags to determine if a block is a log; it should be compatible with any biome mods that have their log types added to the Minecraft log tag.
