Blood Magic

**Blood Magic** is a feature that is unlocked by defeating boss 37. It uses magic and gold for rituals to produce blood, which can then be used to cast magic spells.

Most players will begin by using the cheapest and essential spell, "Blood NUMBER Boost", to bolster the rebirth multiplier. The other spells will become avaliable as your gold production increases, enabling to boost GPS, drop chance, adventure stats, and MacGuffin Fragments.

## Blood Rituals

There are currently 8 rituals to convert gold into blood.
Each blood ritual costs 200 times more gold than the last one, except for the second ritual "Fifty Papercuts", which costs about 333 times more than the first ritual "Poke Yourself with a Tack".
Each blood ritual takes 10 times longer than the previous one.

For evil difficulty, the magic requirement is 1 billion (1e9) times more than the normal magic requirement.

The following table shows you only ratios, and NOT exact values - It's a way to compare the rituals with the previous one, but not actually knowing exact values like "How much blood will I produce in one hour?", since those will depend on the magic power and allocated amount.

Note: From this, lower tier is more gold efficient which is useful for certain challenges, higher tier is more time efficient when you have enough gold to run them.

## The Spells

Spells which give permanent bonuses have a cool down period, all the other bonuses apply to the current rebirth.

Each blood adds 1 to the NUMBER multiplier. This bonus is indicated as "Blood magic bonus" in the rebirth window.
