There was a rank difference between these 2 gems. So, if Abel wanted to make a perfect skull, he needed to combine 81 "chipped skulls" together.
If he was to use a "flawed skull," he would need 27of them.
Abel let out a long breath of relief. It seemed like he needed to kill more deities to get these resources. If his family knights had weapons with these skulls, they could replenish their lives during battle and increase their power dramatically.
Even a head commander could get a lot out of these skulls since head commander skills needed to be infused with mana. If they could replenish their mana, they wouldn't need to rest. That was why only old head commanders with enough mana store would actually use those head commander skills.
However, if they had a weapon with these skulls, their power could increase at least a few times.
The only thing was that Abel never heard of people making weapons out of these skull gems.
