Runic Impression
Your unarmed attacks or weapon gain the benefits of a weapon rune you choose when you cast this spell: Corrosive, Flaming, Frost, Ghost Touch, Returning, Shock, or Thundering. If you cast runic impression on a weapon, this spell ends if you cease holding the weapon, with the exception of throwing a returning weapon. If this spell would give a weapon more property runes than its normal maximum, one of the existing property runes (you choose) is suppressed until the spell ends. For unarmed attacks, if this spell would give you more property runes than you could have from handwraps of mighty blows , one of the existing property runes is similarly suppressed.
Heightened (8th) Add keen to the list of runes you can choose as well as the greater types of Corrosive, Flaming, Frost, Shock, and Thundering.

Traits
Focus spells are a special type of spell attained directly from a branch of study, from a deity, or from another specific source. You can learn focus spells only through special class features or feats, rather than choosing them from a spell list. Furthermore, you cast focus spells using a special pool of Focus Points—you can't prepare a focus spell in a spell slot or use your spell slots to cast focus spells; similarly, you can't spend your Focus Points to cast spells that aren't focus spells.
