Decreases the floor clipping by the number of map units stored in special2 each call until it is fully revealed. When revealed, the first argument is set to 1 (raised) and if the second argument (bloody) is non-zero will jump to the BloodThrustInit2 state, otherwise jumps to the ThrustInit2 state.
The function has a 16% chance of spawning dirt particles in the same manner as A_WraithRaise.
Finally, special2 is incremented by one to increase the speed.
This codepointer is restricted to ThrustFloor and derived classes.
