When the Giant Poison Gas Ant is threatened or attacked, it will turn its abdomen toward its attacker to emit a paralysis gas.  Any target within 10' of the ant must save or roll on the following table: [d6]

1. Suffer a -1 to AC from cramping
2. Suffer a -2 to AC from nausea
3. Suffer a -4 to AC from vomiting
4. Become slowed
5. Become stunned (fall down, unable to defend self, no actions for 1d4 rounds)
6. Become paralyzed (as ghoul)

When gas is sprayed, there is a 1 in 4 chance that an additional 1d3 Giant Poison Gas Ants will be attracted to the area to join the fight.  Gas effects last for 10-40 minutes.

Should a target fail additional saves vs the gas, only rolled effects higher than the current effect will occur and the new effect will supersede the previous effect.

For example, Harrack the fighter has failed a save.  He rolls a 2 on d6 and is now nauseous and -2 AC.  Two rounds later, he fails a second save.  He rolls a 1.  No effect (1 is less than 2).  The next round, he fails a third save.  He rolls a 5.  He is now stunned (5 is greater than 2).
