Two bosses are capable of performing the "Flesh to Stone" spell which, as the name implies, turns the player to stone. Besides, some chests have traps with the same effect.
In all cases, when the attack happens, a white-pink looking orb is summoned. It takes a little to charge and then shoots a white-pink beam. If the beam contacts with the player, the petrification begins. If the player was jumping, they're knocked down and the petrification begins once they get up.
The petrification has three stages: the first one, in which only the legs are petrified; the next one, in which everything up to about the breasts/chest is petrified, and the final stage in which the petrification is complete. The character looks slightly confused in the first stage, and then more and more terrified in the subsequent stages. The unpetrified parts may keep on moving untill the end (specially if the players shake their joysticks in order to break free).
Additionally, if the character's health is low enough when they are hit by the "Flesh to Stone" spell/trap, instead of going through the petrification process, it will skip to the final stage where the character is immediately transformed into stone as a direct consequence of not having enough HP to survive this attack.
The resulting statue looks somewhat unpolished, more rock-like than statue-like.
In Dungeons & Dragons: Shadow Over Mystara, two bosses (Man Scorpion and the Beholder) are capable of turning players to stone with the "Flesh to Stone" spell. The player has the ability to shake the joystick back and forth to break free. Should they not act fast enough and petrify completely, the player immediately loses and must spend credits to continue. This can also happen when the player's character does not have enough HP to survive the attack.
The Magic User player class can also learn this move at level 6.
Dungeons & Dragons: Shadow Over Mystara was an arcade game released in 1996 and has been rereleased on the XBox 360, PS3, PC, and Wii U as part of the Dungeons & Dragons: Chronicles of Mystara two-game package.
