Looking at the list of five…. Four skills, Lumen went into deep thought contemplating which skill would be best for him in his current situation.
He didn't even consider the fifth option the system gave him as a part of the list, clearly the system was in the mood for jokes with Lumen yet he wasn't amused.
The Concussive Strike skill looked relatively simple when reading through the description - channel his body's strength towards the tip of his spear in order to deal a devastating and powerful blow to the target.
But he also contemplated the power that he would actually achieve through this skill. The description of it didn't go into any specifics on the actual damage it would cause, causing him to consider whether it would even be able to match up with his other spear skills like his Mana reinforcement or fire infusion skills.
