The bars over top of your health bar shows the current boost level from using consumables. Each bar corresponds to a different level of boost:
- Level 1:+1% Health Regen per 8 Seconds
- Level 2:+2% Health Regen per 8 Seconds
- Level 3:+3% Health Regen per 8 Seconds and +2.5% Movement Speed Bonus
- Level 4:+4% Health Regen per 8 Seconds and +6.2% Movement Speed Bonus
You can increase the your boost level by using the following consumables (See image below more more detail):
- Energy Drinks: 1.5 bars of boost (40% of total boost)
- Pain killer: 2 bars of boost (60% of total boost)
- Adrenaline Shot: 4 bars of boost (100% of total boost)
One thing to keep in mind is that the effects of using the consumables is cumulative, so drinking two energy drinks will get you to around 80% of your boost bar (slightly less, as the bar degrades while you drink the second energy drink).
