Went and clicked the damage section in the Wiki. It eluded to poison but didn't give any specifics: http://wiki.spiralknights.com/Damage
Add some status effects on there, besides the main damage from weapons.
- stun
- shock
- fire
- curse
- poison
- sleep
- freeze
As I see it the Damage page is for player caused direct damage, while the Status Effect page covers the aftermath(successfully inflicted status). Though there probably ought to be a link to each other, at least in the see also section.
