Salve and recovery can stay. Warlock automatically disables salve while the infection is active, and he won’t punish you for your prevented regen being stronger due to recovery. Granted they’re mostly useless in this fight so you can remove them and invest the points elsewhere if you want, but I personally took off just willpower and didn’t invest the point(s) anywhere else so that I didn’t have to spend units to reset my masteries twice, I just reenabled willpower once Warlock was dead. Remember that you will want willpower back on for the following Nick Fury fight anyways.
For which Carina Challenge?
