(Jake's PoV)
Though other attributes also play an important role, Speed is the main attribute. If I find any attribute treasures, I would surely bring all attributes closer to each other if there was a huge disparity in the future, just like I am doing with those elixirs that the academy is providing the S class students.
For now, except for INT, the other three are closer to each other. So, my concentration was only on improving that.
When I reach Rank-4, these arrows won't work on monsters. I need to get Arrow Skills to hunt then and that means INT and Energy Points (EP) are crucial at that time.
The EP value was very good as it depends on STR and STM.
While in battle EP recovery rate plays an important role too. As it was dependent on INT, increasing INT, the rate of EP recovery also increases. So, no problem over there.
