Blood Runes
There's lots of different runes. They do cool stuff! Try mixing and matching to see what works best for you.
Acceleration Rune
The Acceleration Rune increases the rate of a couple operations. While normally the operations of the Charging Rune and Displacement Rune occur every 20 ticks, one tick of the delay is removed per rune, down to a minimum of 1 operation per tick.
With some Netherite Scrap and some Intricate Hellforged Parts looted from the Demon Realm, you can double the power of your Acceleration Rune, removing two ticks per rune instead of one, freeing up other slots around your altar.

With some Netherite Scrap and some Intricate Hellforged Parts looted from the Demon Realm, you can double the power of your Rune of Capacity, increasing the capacity of the Blood Altar by an additive +40% per rune.

Charging Rune
The Charging Rune is a unique Rune upgrade. When the Blood Altar is neither crafting nor filling a Blood Orb, it will syphon LP from the Altar to charge an internal buffer. When an item is next placed inside of the Altar, it will instantaneously consume the stored charge and apply it to the crafting of the item at a 1:1 ratio.
The Blood Altar does a charging tick once per 20 in-game ticks, which is reduced by 1 per Acceleration Rune.
The speed that the Blood Altar charges at per charging tick is:
10LP x Charging Runes x (1 + Speed Runes / 10).
The maximum charge that a Blood Altar can hold is 1000 LP per Charging Rune, which is then multiplied by:
(capacity of the main Blood Altar tank) / 20000
If that value is above 1.
With some Netherite Scrap and some Intricate Hellforged Parts looted from the Demon Realm, you can double the power of your Charging Rune, both in terms of capacity and speed.

Displacement Rune
The Displacement Rune increases the flow rate of Life Essence into and out of the altar when pumping to and from an external Tank. The formula is x1.2^(runes).
With some Netherite Scrap and some Intricate Hellforged Parts looted from the Demon Realm, you can double the power of your Displacement Rune, increasing the flow rate by a multiplicative +40% per rune.
