Upgrade those items via recipe would also be an alternative, with a LV7 required on alchemy and a pile of other items and crafting materials just to balance on how they're 'made'.

But I really want to make things as simple as possible. The end justifies the means, I say. Either way people will be getting those one way or another, so why not make it simple buffs instead of giving us and Dev more work? I've went on that logic.

As for Blood Whistle, I just felt like it would fit. This was one of my ideas, the other was to make it heal you for 5 HP when you hit an enemy with wind damage and they don't resist.
The wind cap increase was dubious at most, I wanted to make Blood Whistle one of the accessories that allow you to go over the cap, a la Dragon King set. But the original plan was to make it increase CEL (or Wind ATK) by 10%.
