The Salad foods that give % more damage while moving are still not working.
This is a long-known bug. I tested it long ago, and tested it again today.
Setup: No boons, no stacks, using water attunement scepter auto attack (3 projectiles with no conditions) to kill Flame Legion Blademasters. Crit damage = 53%
First run: no food, standing still. Averages of regular attack damage; crit attack damage are as follows
regular attacks did 95.756 damage avg
crit attacks did 195.154 damage avg
Second run: Bowl of Asparagus and Sage Salad (8% damage while moving). Moving the entire time.
regular attacks did 95.909 damage avg
crit attacks did 195.818 damage avg
Third run: Same food, but standing still while auto-attacking the enemy to death
regular attacks did 95.421 damage avg
crit attacks did 196.143 damage avg
As you can see, nothing is having any effect on damage done.
