# YTech<\/p>\n
brings you to Stone Age, increasing difficulty on early game by forcing you to use primitive technology for progression.<\/p>\n
Also, vanilla mobs like cows, pigs, sheep and chickens are replaced by their wild ancestors.<\/p>\n
Vanilla recipes for early game items are modified, forcing tools on some blocks and adding new tools, items and blocks to help you with progression.<\/p>\n
Currently mod covers
\n– Stone age
\n– Bronze age
\n– Beginning of iron age (crafting iron ingot is final step right now)<\/p>\n

## Hints<\/p>\n
> – You can’t mine wood and dirt without correct tool
\n> – Your first goal is to find flint and hit stone with it
\n> – Grass fibers can be obtained by breaking grass with sharp flint
\n> – Look for deer, you need it for your first pickaxe
\n> – Only deer with antlers drops correct item
\n> – Primitive Smelter and Primitive Alloy Smelter needs chimneys for increasing temperature
\n> – Each type of chimney can be up to 4 blocks high, otherwise it collapse
\n> – Using reinforced chimney you can increase height up to 8 blocks, with 4 of each chimney
\n> – Lead and Cassiterite can be gathered using Strainer
\n> – It’s recommended to use JEI
\n> – You have to breed wild animals to get their domesticated versions
\n> – Aurochs -> Cow
\n> – Mouflon -> Sheep
