Originally, when Raze had gotten the statue, it had become a sealed item. It was cursed, but once the seal was broken, the item would no longer be cursed.
Similar to Simyon's earring, the curse was more of a simple one. Raze just needed to get the blood of five different people.
Due to the word curse, he thought that something might happen to the five who placed their blood in the statue to unseal it.
It turned out that there was no problem at all, just the fact that it needed blood. So, when he found out the statue's effects, he was a bit disappointed.
At the time, nearly all of the students were second-stage warriors, so the strength of the statue was just a little under what Dame's strength was.
It was a good tool to have, but in the future, it would just get weaker and weaker, which was why Raze was a bit disappointed by his actions, that was until now.
