Jack didn't use those items right that moment. Instead, he dealt with his free attribute and free skill points first. He had 24 free attribute points, 9 free skill points for Brave Swordsmaster and Time Sage, and 6 free skill points for Beast Monarch.
He also checked his Container of Souls. The container had 6,900,000 souls inside. These were the souls gained not only from the recent battle but also from the maze under Sangrod royal mausoleum and the souls from Emperor Marcus' death.
He spent all 24 free attribute points on his Endurance, increasing this attribute to 2,420 points.
He then spent Brave Swordsmaster's 9 free skill points and 100,000 souls on Ghost Sword. This skill was fully maxed to level 20. The skill now lasted a half minute.
He still had the Field of Swords at level 1 but he decided to leave that skill for now.
