Jack Cada was a happy blitzer in Lautrehamon's team "green poets"
He was the strongest and fastest, while also being quite agile, an absolute freak of nature. He unfortunatelly passed away after trying some heroics and receiving a claw hit to the face. Our "beloved" team's necromancer Chov claims that this time it all happened too fast and that it is not his fault that this not-so-dead-anymore orc is still behaving like a blitzer (although there is evidence that he was sleeping while the death happened and that he performed his craft half sleep)

Regardless, Jack still behaves like a blitzer, and as such, his first normal skill will be block.
