Effects

Effects are the icons on your HUD: buffs that help, debuffs that hurt, and conditions that just tell you something about your body. Times are play time. Taking the same thing again usually restarts the timer at the longer time; Sick adds up instead.

Percentages are changes: “move speed −10%” means you walk 10% slower while it lasts.
