Healer's Friend (and recovery effects) unfortunately do not apply to Regen or Vis. That said, the initial heal should still be boosted; I'll look into this.
EDIT: Found out the issue. Another easy fix- a loop was stopping one ID early. I'll have a third patch out soon!
Anyway, spoilers:
I actually got the number wrong on Despondent. It was 20 buffs, not 10. Sorry- it was a pretty hectic day yesterday.
