Dice results:
* A critical success will double the length of the smoke tear gas cloud's life (6 turns instead of 3 turns). If it was aimed at any particular creature, the GM may, at their discretion, deal a small amount of damage to that creature; a tear gas grenade landing on someone's head or exploding in someone's face is rarely pleasant.
* A regular success will result in the normal effects of the tear gas cloud occurring.
* A failure still results in a tear gas cloud occurring, but for only 1 turn instead of the normal amount.
