I believe, that the Kardia Heal from Eukrasian dosis is wrong. As Eukrasian dosis is damage over time spell, so the Kardia heal from It should be heal over time.
So for every tick of the eukrasian dosis dmg, the kardia heal should return appropriate ammount of healing. Now It heals instantly for the sum. It would make sense and give a missing hot heal to sage.
