Invariability

The caster carefully places the four cogs around the target and traces chalk lines connecting them. As the chalk lines must be as close to perfectly square as possible, the caster typically uses a guide or straight edge to draw the lines, although these components aren't strictly necessary if the caster can draw the lines freehand with exceptional precision. As the caster recites certain mathematical formulae, the cogs slide slowly along the chalk lines and closer to the target, redrawing the chalk lines across the floor as they move. As the cogs approach the target, the target's skin and clothing become more metallic-looking, and the target's gaps and joints appear to contain rapidly whirring clockwork mechanisms, as though the target were a quasi-mechanical creature like an inevitable. If the ritual is successful, the target is infused with the essence of Axis and can act only with rigid precision. The first ability check, attack roll, caster level check, saving throw, or skill check the target makes each round throughout the ritual's duration is automatically treated as though the natural d20 roll resulted in an 11. When the duration ends, the target's appearance returns to normal.
