Okay, it clearly states in Init Data that magic is 32 per block. But the game treats spell usage as double the normal amount until you half it. So a single magic container without half magic upgrade is treated as 16 until you get the upgrade. We need to change what is said in Init Data so that it's 16 per block, and not 32. Or is there a reason for it being 32? I don't know, it's all so confusing.
ZQuest Inconsistency
According to its default data in the item editor, its increase amount and + Max are both set to 32. But the point is, the Magic Cost is nx2, meaning that if it is set to 1, it uses 1/16 (2/32) of a magic container. Same deal with how a weapon's damage is nx2, meaning that if the damage is set to 1, it deals a damage of 2 HP to enemies. On the other hand, when Link receives damage from enemies or projectiles, the damage is nx4, meaning that if it is set to 1, the damage is 1/4 (4/16) of a heart.
