Anamnesis

You touch a creature and identify any non-magical disease and any magical disease or curse created by a 1st level spell that is affecting it. If the disease or curse is caused by a higher level spell you sense its presence but know nothing of its effects or possible cures unless you succeed on an ability check with your spellcasting ability (DC = 10 + the spells level).

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher you can identify magical diseases and curses created by a spell of equal level than the spell slot you expended.
