Nice pace! Keep up the good work! I don't know if it wasn't mentioned earlier, or if I just didn't remember Nädel's family name, but I was very amused about it! (for those, not in the know, he is literally named "Needle Thread")
But may I suggest, expressing the Mana cost over time as "M/s" or "MP/s" instead of "m/s"!? Because the later is used to measure actual speed, as the mathematical abbreviation for "Meters per second", which is confusing for people who actually use that value frequently! 😉
