The Powers of Blood
Everyone knows that Blood is a key element of every living being. Combining the magical properties of Dark Gems and the vitalizing Blood allowed me to come up with some really amazing new tools and machines. Some of my peers say I’m a bit too enthusiastic about this discovery, I guess they’re not open-minded enough.
Dark Gems seem to be very open to accept Blood. Tossing one in a pool of Blood results in a Dark Power Gem. Note that you will need at least five source Blood blocks in the world, you will need to do this at least once, in the next chapter I will explain how to more cheaply craft Dark Power Gems. When tossing your gems in the pool of Blood, make sure you aim at the source blocks.
As we all know, Blood will dry out after a while when it is in a dry area. Breaking the Hardened Blood with a pickaxe or your fists will turn it into regular Blood again. Breaking such Hardened Blood with Flint and Steel will give some Hardened Blood Shards which might come in handy later on. It looks like these shards can also be obtained when cooking such a Hardened Blood block, if you can obtain it in some way ... maybe a soft touch can help?
