The debuff applied by Biochemist Doffs has been re-designed:
This debuff no longer stacks.
The duration no longer scales with Duty Officer Quality, and is always only 5 seconds.
The Resistance Reduction now scales with Duty Officer Quality:
White = 10%
Green = 20%
Blue = 30%
Purple = 40%
This still has a 60 second duration. It is, however, NOT stacking anymore.
