The Shedim Champion worsened its injuries by smashing itself into the ground. It intended to bury Liam beneath it, squashing him to death but that plan failed miserably.
Its' wings were broken and its back felt numb. Several spots of the Boss Monster's upper back were petrified, precisely everywhere around the cuts, which Liam had inflicted with the Arcane Kunai.
The Petrification Poison Rune would stay active for more than 25 minutes which it could be used as long as Liam provided enough Arcane Power to keep up the effect.
His lack of Arcane Power was the biggest problem but that could be temporarily substituted with potions. He had still enough Arcanium to buy three potions, if necessary.
But while the Shedim Champion was already injured and bleeding severely due to the various small cuts, turning those spots to stone, Liam was not exactly unscathed either.
