The original version of the game had description for the different enemy affixes in a separate window. I was kinda balancing whether I should keep that or not but decided on to not have them be visible and tried to make effects be a bit more easily noticeable themselves. But not, that wasn't enough and now the descriptions are back, but in a bit different way.

So there is this separate scroll menu where you can view info for the enemies and their effects. But the effects will not be unlocked on your first encounter with an enemy. When you've already seen an enemy affix at least once, even if you lost to the enemy that had it, its effect will be shown completely on the menu.
