When approached w/in 10' the creeper attacks, puffing dust/spores into its victim's face. Victim must save vs. Magic or be entranced and walk into the mass of the plant, resisting any attempt to restrain him and taking the remainder of the melee round to do so. Once in the heart of the plant, the aerial roots burrow into his skull and eat his brain at the rate of 1d4 Int. points per round. So many roots attach to a victim at once that attacking the roots individually has no chance to save the victim. The only way to kill the 'creeper is by stabbing at its bulbous root buried 1" below the surface of the earth.
If the victim's intelligence is reduced to zero by the 'creeper, the victim dies, but if his intelligence is reduced to 1 or 2 points then he immediately becomes a Yellow Musk Zombie. Each creeper will have one Yellow Musk Zombie for every two flowers. Intelligence loss in tose not transformed into y.m. zombies is temporary and will be regained at the rate of one point per day of rest.
Heal restores all lost intelligence immediately.
