There are all sorts of medals that have very vague descriptions of how their multipliers work. For example, the Aqua and Stitch medal says the multiplier is increased based on how many special attacks are used in succession but it does not say how many special attacks are needed to reach the max multiplier for it. Does somebody have a website or a link or something that clarifies these vague multipliers and if not can someone at the very least tell me how many how many special attacks are needed to top off the multiplier of Aqua and Stitch.

A lot of these can be found on Reddit, though it would take a bit of looking. If I recall correctly, I believe you would have to use 4 special attacks, meaning you would need the Aqua+Stitch medal in the 5th slot of a Keyblade. You could also put it in the 3rd slot and have the first 2 medals be medals with the extra attack trait.
