Hallucination Cloud (Ex)

As a standard action once per minute, a basidirond can release a cloud of invisible spores in a 20-foot radius. All creatures within the area must succeed on a DC 16 Fortitude save or be affected by powerful hallucinations as long as they remain in the cloud plus 1d4 rounds after leaving the area. A new save must be made each round a creature remains within the affected area. A hallucination cloud persists for 5 rounds before dispersing—a strong wind causes it to disperse immediately. The save DC is Constitution-based. To determine what hallucination is suffered each round, roll 1d6 and consult the following table.

d6 Hallucination

You're sinking 

in quicksand! Fall prone and spend 1 round flailing your arms and legs as if trying to swim.

Attacked by a swarm of spiders! Spend a full round action to attack the floor near you with your weapon.

An item you hold has turned into a viper! Drop it and flee from the item at top speed for 1 round.

You're suffocating! Stand in place, hold your breath, and clutch at your throat for 1 round.

You've shrunk to 1/10th your normal size! Take no actions for 1 round and monsters won't see you.

You're melting! Grasp hold of yourself in an attempt to hold yourself together, and take no actions for 1 round.

Spores (Ex)

Any creature struck by a slam attack is coated with spores. The creature struck must make a DC 16 Fortitude save or these spores take root in his flesh, and particularly in his lungs. The save DC is Constititon-based. 

Spores: Disease—inhaled; save Fort DC 16; frequency 1/round for 6 rounds; effect 1d2 Con damage; cure 1 save.
