You scribe a potent rune of power in the air. When the symbol is activated by a target approaching, all nearby targets are panicked for 6 seconds per caster level or until the symbol expires. A successful Will save negates this effect. A symbol will persist for about 5 minutes until triggered. Once triggered, a symbol's power begins to wane. A symbol will dissipate 20 seconds after first being triggered. Symbols are volatile when placed together.
