Gorgon's Glare (3.5e Spell)

''You hold aloft a polished stone eye, which seems to twitch around angrily on its own. With a baleful crimson flash of light you curse your foes, as dust in the air and the earth below turn against them, encasing them in shells of rock.''

You curse your opponents to a petrified fate. All targets within the cone shaped burst must make a fortitude save or be petrified as per Flesh to Stone. Even on a successful save however, the subject loses 10 ft to it's speed, and 20 ft to any fly speed it possesses, and must make a fortitude save every round, or lose another 10 or 20 ft to its speeds, save negates. Succeeding on 3 saves in a row ends the spell for that creature, otherwise it continues until all speeds reach 0 ft. When this occurs any further fortitude saves are against the petrification effect until they fail, or the duration ends.

Creatures with the earth subtype are not affected by this spell, while creatures with the air subtype gain a -2 penalty on saving throws.

Focus: A polished stone carved into an eyeball worth 1,500 gold.
