This spell functions like symbol of death, except that all creatures within 60 feet of a symbol of stunning instead become stunned for 1d6 rounds.
Unlike symbol of death, symbol of stunning has no hit point limit; once triggered, a symbol of stunning simply remains active for 10 minutes per caster level.
Note: Magic traps such as symbol of stunning are hard to detect and disable. A Rogue (and other characters with the trapfinding class feature) can use the Search skill to find a symbol of stunning and Disable Device to thwart it. The DC in each case is 25 + spell level or 32 for symbol of stunning.
Material Component: Mercury and phosphorus, plus powdered diamond and opal with a total value of at least 5,000 gp.
Note: The 3.5 manuals do not include the paragraph regarding the duration of the spell, unlike all the other symbol spells which affect all creatures, but this is obviously an omission.
