This ritual node comes into play with invisible mystic runes protecting it. The explosive runes detonate when a player attempts to scrub this ritual, dealing [5/6/7/8/9]d6 points of force damage. Anyone next to the explosive runes (close enough to scrub) takes the full damage with no saving throw; any other creature within 10 feet of the explosive runes is entitled to a Reflex save for half damage. The ritual is immediately scrubbed.
