Fervour is used to cast Prayers or perform special attacks. It is gained either by striking enemies with Mea Culpa and executing them, recovering a Guilt Fragment, performing a Blood Penance (Blasphemous 1) or the verse Cabal of the Deep Wound (Blasphemous 2).
Every time the Penitent One dies, his maximum amount of Fervour will be restricted, as his Guilt increases. To recover full use of Fervour, he must recover the Guilt Fragments or Confess.
Blasphemous 1[]
The Penitent One can increase his maximum Fervour by anointing himself with the Oil of the Pilgrims.
Blasphemous 2[]
The Penitent One can increase his maximum Fervour by giving Fervant Kisses to Besamanos in Streets of Wakes.
