Demonic Training (2)

One point in intelligence gives exactly 10 points in mana, whereas an entire day's training in mana manipulations and meditation will get you or two points at best. Where's the other physical stat such as Strength, agility, constitution, endurance or resistance—every one of them grows at least four or five times faster with proper training, though it needs to be considered after all of them reach 50 mark, it would be far harder to train physical stat than mental stat.

Another magical thing about physical attributes was that they were connected. Surely if your constitution rose, it would be followed by your strength, agility, and vice versa. Similar things happen in between perception, intelligence, though it was on a marginal level.
