Spermsteel

Spermsteel is a miraculous material expertly forged using Godsperm and ambrosia. This metal appears solid white and glistening, sometimes with a soft white glow or electric crackle. Unlike most forms of Your Godsperm, spermsteel is inanimate and incredibly rigid. This legendary metal is thought to be nigh-invincible, capable of producing the sharpest blades if it is worked properly.
  Valkyries and many other sluts dream of donning spermsteel armor or wielding spermsteel weaponry. The legendary warriors privileged enough to wear a full set of spermsteel are called spermknights, and gain supernatural power from the sperm within — including the ability to harness sperm-lightning to an extent.
  Despite the power of spermsteel, we assume You would be more interested in slut-equips than wearing Your own Godsperm.

Formation

Exceptionally skilled sluts are sometimes capable of forging spermsteel using specific forms of Godsperm, especially frozen spermeteors. The precise means of forging are nigh-mythical and surely arduous.
  We believe You are capable of consciously producing shaped spermsteel with a fucknuke. For example, merely by fucknuking upon a slut, if You will it so the Godsperm upon her spontaneously hardens into an ornate suit of spermsteel armor.
