>>6058308>The fish girl is struggling too, maybe practicing with someone more your speed is better?TLDR, make the easiest frens, because frenship is magic, and personnel capital.
long version:
UM training can be any time Table is available. Since this is the start of the academic year we will need to make a good general impression, so that we can gain access to everyone's innate specialties.
Practicing with the fishgirl is best because she is floundering for 2 or 3 lessons now; if we befriend her at this time she will remember it positively, and when the lesson with her native type of magic pops up she can pitch in and volunteer information or intuition. Call it an investment: genuine gratitude usually pays back twofold at least.
Raw mana might seem like the issue for Atlas, but since he knows the UM hack at a fairly young age it should not matter significantly in his magic career. Like the discoverer of UM, Atlas should be going for understanding and efficiency. Barring artifacts or special events Atlas will never have enough mana to brute-cast; his focus should be on elegance. Learning magic through partners with magic affinity has a good chance of that.
