What would happen when rakna's tail clones eat each other's hearts. Here are some examples of what I think would happen in each variation. clone A eats the heart of clone B: clone A's power doubles. clone A and B eat each other's heart: they both explode resulting in permanent loss of power. rakna eats the heart of one of his clones: rakna gradually gets stronger over time however he also becomes a ticking time bomb that can be defused by reabsorbing the tail.
