Runesmith

''The Runesmith enchants your zombies with magical symbols of life and death. These runes can be infused with resources to increase their power.''

Runic Syphon
''Infuse your runes for free! Each rank gives your Runesmith the ability to infuse 1% of your resource income, without consuming it. Additionally when blood and brains reach their storage limit, any additional resources will be infused automatically.'' You might want to hold off constructing Bottomless Pit until done shattering runes.

Without Runic Syphon there would be no automatic infusing unless storage limit is reached.

Rune Shatter

First gives 110%, second gives 121%, third gives 133.1% and so on.

-A note for those confused as to why rune shattering is good. (Not part of the usual wiki team, just a player)

Rune shattering gives exponentially increasing buffs to both HP and DMG (the 10% is not additive, it multiplies the previous multiplier), allowing for potentially infinite growth. Not only that, but the runes seem to have 'break points' where each added resource stops being as effective over time, practically forcing the player to find some way to invest more. Another point is that the only runes with no (known) limit to their potential are attack speed and crit dmg, after a certain point in the game the amount of resources needed to max out any particular area are practically given to the player instantaneously after the shatter, and at that stage the humans start scaling insanely high.
