1) Ennervation
- Small boost to 40(+) Monks, Knights and Rangers:

• At 40 piety, you can no longer bless under +20
  At 50 piety, you can no longer bless under +25
  At 60 piety, you can no longer bless under +30

This affects every class, but there's no gain to Priests, as they bless a lot more than listed above with 40, 50 and 60 piety.

2) Intervention
- Intervention is now easier to cast for Knights/Rangers.
