I'll use this as permission to answer.

Lethargy: victim becomes burdened, loses dex, and movement regen is lowered
Vertigo: victim loses intelligence, targeted abilities have a chance to target random person
Cowardice: victim has a chance to flee every round of combat, loses morale
Despair: victim loses strength, defenses become worse, loses morale
Nausea: victim loses con, chance for attacks to fail

This ability's duration is measured in rounds of combat rather than hours of game time.
The lack of information on the affect list was intentional, so the victim doesn't know which hypno affect you went for.
