Can a mage use Counterspell or Dispel Magic to counter the effects of magic items?
Counterspell and Dispel Magic are fine for removing magical effects cast on someone by a caster who is empowered to cast spells via a magic item. They have no effect whatsoever on magical effects affecting the wearer of an always-on item. For instance, a Sickness arrow makes the target sick until the arrow is extracted, but a Sickness spell cast by a mage wielding a staff enchanted with Sickness can be Dispelled normally.
