7	Whispers of Apophis	Curse (Spell)	WIS Check (CL 3): Target hears continuous, maddening sibilant whispers. They cannot benefit from full rest to regain spells or HP, and suffer a -2 penalty to all Mental SIEGE checks (INT, WIS, CHA).
8	Mark of the Serpent God	Curse (Touch)	WIS Check (CL 2): An branded cobra tattoo appears on the victim's chest. All reptiles automatically treat the victim as hostile and gain +2 to hit them.
9	Curse of the Sunless Sands	Curse (Relic)	CON Check (CL 4): The victim's body rapidly dehydrates. Requires 4x the normal daily amount of water; failure to drink causes 1d6 damage per hour and severe exhaustion (-4 to all checks).

These tomb-guarding curses are triggered by disturbing glyphs, breaking sarcophagus seals, or opening trapped doors within Sethic crypts. Designed for Castles & Crusades, each curse requires a SIEGE Check to resist or mitigate, with the Challenge Level (CL) scaled to the tomb's severity.
