- Casting Time: 1 minute; Somatic and Verbal
- Range: touch
- Target: 1 object with writing of 5 bulk or less
- Duration: indefinite (D); see text
- Save: Reflex save; see text
You trace runes on the object such that, when the object is read, they explode. The creature reading the rune along with the object take a number of d6s force damage equal to half your Proficiency Score with no save. All those within 10 feet of the object when the runes are read must make a Reflex save. On a success they take half damage.
When you cast this spell, you can determine any creatures that may read the writing without exploding the runes. You can dismiss the runes whenever you want as a free action. Only an Erase spell can attempt to dispel Explosive Runes. If another source of dispelling attempts it, or the Erase spell fails, the runes explode as if the cause of the dispelling attempt had read the object. Once the runes explode or are dispelled, the spell ends. Exploding Runes are on the Arcane Spell List.
