Question: How do you know if you run out of mana?
Correct answer: Each mage has a different way of telling, depending on how well their mana control is. However, the common symptoms of running low on mana are head-dizziness and fatigue. That usually happens when you have 1/10 of your mana total left, depending on whether you treat it as a pool or a rectangular vase.
Result: Both Zofia and Ashrosaliera got a point.
Ashrosaliera raised her hand.
"Yes?" Thuong asked, eyes up from reading the answer sheet.
"What do you mean… Pool or rectangular vase?" Ash asked.
