Talk:Type 1 Armor Piercing Shell/@comment-26373693-20150529055431

If anyone's curious, I did some calculations on how expensive these things are to get and upgrade. Creating one and getting it to the max upgrade level requires a total of 52 type-91 AP shells, assuming every upgrade attempt is successful. Assuming you're using the 10/30/90/10 recipe with a 4% chance of success, this will cost 13k/39k/117k/13k and about 1300 development materials.

That's a little depressing.
