Symbol of Striking
School illusion (shadow); Level cleric 5, magus 5, sorcerer/wizard 5, witch 5
Components V, S, M (a masterwork melee weapon costing at least 300 gp)
Saving Throw Will half, see text; Spell Resistance yes, see text
This spell functions like symbol of death, except that using the material component, you scribe a symbol of striking so it fills a 5-foot square. Once triggered, the symbol of striking glows and lasts for 10 minutes per caster level or until it has made a number of attacks of opportunity equal to your level, whichever comes first. When triggered, the symbol threatens its area and the area around it as if it were a Medium creature wielding a magic version of the weapon you used as the material component. Using your caster level + 1 + your Intelligence modifier (magus, witch, wizard) or Wisdom modifier (cleric) or Charisma modifier (oracle, sorcerer) as its attack bonus, the symbol can make a number of attacks of opportunity each round equal to 1 + the same ability score modifier you used to determine its attack bonus. It gains a bonus on damage rolls equal to the same ability score modifier you used to determine its attack bonus. A shadowy version of you wielding the material component appears to make these attacks.
The symbol attacks any non-attuned creature that provokes an attack of opportunity from the symbol. However, when the symbol first attacks a creature, the symbol must overcome that creature's spell resistance or be rendered unable to harm it. The symbol never again attacks such creatures. Further, when the symbol first attacks a creature, a successful Will saving throw allows the creature to see the shadow nature of the attacks and take half damage when such attacks hit.
