For the Scion-of-High-Sorcery mythic paths from Mythic Paths of the Lost Spheres:
Sanguine Rune (Mythic)
You may use your blood’s magic to enspell a weapon it anoints.
Prerequisites: Sanguine Elixir mythic path ability
Benefit: You may can expend a use of mythic power as a full-round lay a spell in wait on a melee weapon in a manner similar to a weapon with the spell storing weapon special quality. Spells must be limited by the same level constraints as your Sanguine Elixir path ability. If you have other path abilities that increase the limits of Sanguine Elixir (such as Heartblood Elixir), this ability is also impacted by the new raised limits. Constitution costs remain the same.
