SRD Cure Light Wounds: 'Since undead are powered by negative energy,
this spell deals damage to them instead of curing their wounds. An
undead creature can apply spell resistance, and can attempt a Will save
to take half damage.'
- _apply_heal_effect takes the rolled save; an undead target takes the
rolled healing as damage (halved on a successful save; SR already
resolved upstream, DR never applies to spell energy, no bleeding stop
or stabilization). Living targets are bit-identical.
- cure_light/cure_moderate descriptions fixed: the SRD save line is
'Will half (harmless)', not 'negates'.
- Deafened 20% verbal spell failure DEFERRED to the README « Limites
hors perimetre »: SpellSpec carries no components data (would need a
verbal flag on all 108 spells) and sound-based Perception is not
modeled either.
