Card effect
Whenever one of your heroes triggers a Setup effect, 3 random heroes and the Arcomia Core +1 level.
Skill

Passive: Dolia takes mermaid form inside the water zone she creates. Her basic attacks restore an extra 5 mana and deal an extra 50% magic attack as magic damage. Casting her skill again inside the zone removes the old zone and creates a new one. Active: leaps to the densest group of allies within 3 tiles and creates a water zone for 10 seconds, taking mermaid form inside it. On landing, she instantly heals allies in range for 75+100% magic attack and restores 10 mana (mana restoration does not apply to Dolia). The zone heals allies in range for 50% magic attack per second. When Dolia leaves the zone, it disappears and she returns to human form.
