The meditation ability, as previously established, buffs a person's magic attack power, their mystical and physical senses, and their reaction speed. Additionally, Zack discovered that the meditative state would make him enter a regenerative state, allowing him to heal superficial damage with ease.
The aforementioned buffs would last for an entire day if one meditated perfectly for thirty minutes.
That time limit could be further extended, to a maximum of three days. If you meditated any further, the time limit wouldn't increase, but instead, decrease! Why? Because the potency of the buffs would increase! They started at stage one, and ended at stage five.
Stage five was ridiculously overpowered. Contrasting to stage one's twenty-five percent increase to magic attack power, stage five gave Zack a two hundred percent increase!
