chill touch + dazing spell metamagic

[Meager Rolmug]

Does the dazing affect every successful touch attack or only the first? How about compel hostili
ty?

[SlimGauge]

Dazing Spell affects all creatures damaged by the spell. It doesn't matter if it's a Fireball damaging several creatures all at once, or Chill Touch damaging several creatures over the course of several turns.

Compel Hostility does no damage, and therefore cannot benefit from Dazing Spell.
