Yes, I believe that one of the custom routines (might not be updated) had some custom coding for vaal skills.
I am hoping that these are brought into the new routine. Having a list of vaal skills, then you can select which you use, and then when to use based on % life or mob rarity (5+magic, 2+ rare, 1+ unique) etc. I think this could help with bot survivability and clear speeds as well.
