Ailments and effects
Bleeding, burning, freezing and every positive and negative effect that shows up on the status bar.
Hits can inflict ailments, effects that last a few seconds on the target. Monsters inflict ailments on your hero (each creature's page says which ones and how likely), and your hero inflicts them on monsters through skills, affixes and runes.
Active effects appear as icons above the middle panel of the screen (positive ones in one row, negative ones in the other) and, on bosses, under their life bar. Hover over an icon to see its description and how long it has left.
In the list below, N stands for the value the effect has at that moment (it depends on the hit that caused it).
