You are able to have one buff per channel active at any time. There are 10 different channels available:
- Consumable (boosters/injectors/pills)
- Primary Skill
- Secondary Skill
- Contigency Plan
- Primary Mutation
- Secondary Mutation
The above buffs can be applied to your character through your Action window (or hotbar) and items that can be consumed. There are other buffs available such as the Rest buff you receive from Bunker Bars, the Faction Control Point boost buff and buffs from the Campsites.
