You can have up to 100 points of hate. Afflicted suffer from reduced healing while not at maximum hate -- by 50% at zero hate. Your Hate slowly decays (more quickly when the level is higher), down to a minimum of half your Hate at the end of the most recent combat. The strengths of many abilities also depend on your level of Hate.
Here are some ways Hate is regained:
- Kill something: 8 points, more for higher rank -- 24 points for a boss
- Take a big hit (over 15% of your maximum life): 2 points + 2 points per 5% life lost above 15%
- Take a hit while at low health (under 25% of maximum life): 4 points
- Do massive damage (over 33% in one hit)
