As can be seen in the attached video. Panic: Sword is supposed to drain your Combo Attack bar to do a critical attack. As I've been working on my Ironman I've found it useful while grinding for Rexton leather (A tedious process) one thing I realized though is that when you cast Panic, it updates the icon in the top right to show you have a full time on Combo Attack, but the original timer continues and you have the original combo attack duration. Should be a small easy fix, but since I doubt anyone plays hero and even less of those people have actually ever used Panic:Sword it's something I just wanted to share as a graphical glitch.
It happens with transformation/super transformation when one of it's boosted stat is replaced with another item or skill, but then that thing expires. for example: xform keeps your speed/jump at 140/23. If dash is used to boost your stat, and then you stop moving or turn around, effectively debuffing dash skill, xform will reset itself as the right most icon with no darkening of the icon to signify the cooldown. Happens too, if things like gizer's 30 def replacing xform's 40+ def, then you right click gizer to remove it.
