Since i unlocked the disk i been using it for my Yzma. And i found great this disk until Yzma health reach the under 50% and activate the ability of this disk. Because thanks to this disk her speed feels like is changed from the 1.00 value to .30 (becoming 70% slower in perception) and not the 1.30 speed intended according to the game description.
Is the description wrong or is a glitch @Polaris?
