The cover of the book had symbol of various kinds and they were constantly changing. This was one of the two heart tools that Elena had gotten during the war. The effect of this book was extremely powerful but with a lot of restriction.
This book could release a single spell which would be able to effect even people above the power level of 5000. But the caster had no control over what kind of spell would be released and it also had a long cooldown of 12 whole hours. There is a possibility that the caster might end up healing their opponent instead of hurting them or even giving the opponent a power boost.
