For people who want to work on your RES stat, I suggest using an autoclicker with a delay of 250ms to only click GUARD while fighting against a Harpy(run the autoclicker for several hours). I use android on a fire tablet and used Macrodroid downloaded from Macrodroid. Attatched is my specific set-up for the macro. (Also works on chromebook!) Macrodroid can also be downloaded from the play store. Please ignore the gear symbol, it is just the floating trigger button.
