I just wanted to note that the Blood of Shadows player companion gives some new methods to negate Darkvision and See in Darkness in areas of normal darkness. Makes some types of battlefield control more effective against monsters.
Negates Darkvision only:
1. Deeper Darkness spell. The old standby, but I list it for completion.
Negates Darkvision and See in Darkness:
2. Shadowmind spell (BoS). Levels 2-3 for most divine, arcane, and psychic casters. Creates a phantasm that conditions are darker and hits multiple creatures. If they fail their save this effectively blinds any creature, including those with Darkvision or See in Darkness, if the light conditions are otherwise dim light or darkness.
3. Mydriatic Spontaneity (BoS). Level 3-4 for arcane and psychic casters. Main effect is to cause nausea, but also provides a 50% per round chance to blind in full darkness or bright light. The darkness blinding would ignore Darkvision or See in Darkness due to the physical effect causing it. There's a Mass version at levels 6-7.
Of final note, Blood of Shadows introduces the Eclipsed Spell metamagic. This is a +0 modifer that flips a darkness spell to light, or a light spell to darkness. Effects that increase light by two steps when flipped cause supernatural darkness just like Deeper Darkness, so your Daylight metamagiced with this can shut down Darkvision in conditions less than bright light. This is a great capability for the many classes that have Daylight but not Deeper Darkness on their list if they have the feat to spare.
