Norlian's Numismatic Trap

This spell was designed by a wizard who was often the target of thieves, to turn any chest of coins into a lethal trap for those who would steal it. After inventing the spell, the thefts stopped abruptly. The wizard then sold scrolls of his spell to others, making a whole new fortune.

Effect

You trace mystic runes beneath a pile of coins, enchanting it with a spell of detonation to propel the coins upwards at great speed when they are disrupted. When touched by a living creature, the spell activates and launches the coins immediately upwards at ballistic speed, causing 6d6 points of bludgeoning damage. Anyone close enough to touch the coins takes the full damage with no saving throw; any other creature within 10 feet is entitled to a Dexterity save for half damage. The coins themselves disintegrate into tiny scraps of shrapnel, and are destroyed.
You and any persons you specifically instruct can remove the coins without triggering the runes. Likewise, you can remove the runes whenever desired. Another creature can remove them with a successful Dispel magic or Erase spell, but attempting to dispel or erase the runes and failing to do so triggers the explosion. The coins can, however, be removed by tipping out a chest from a distance, or Levitating them out, for example.
Note: Magic traps such as explosive runes are hard to detect and disable. A rogue can use the Investigation skill to find the runes and Disable Device or Dispel Magic to thwart them. The DC in each case is 25 + spell level, or 28 for explosive runes.
