7. Extra Skills
All Extra skills can be released using Alt + Num key. In general, Extra skills use 100 Focus unless stated otherwise, deal more damage than regular skills, and have separate cooldown. You can use the Extra skill of the same skill even if you just fired the regular one. I'll only list the Extra skills that have special effects. Unlisted skills presumably have no special effects other than more damage.

image Herded Hew (Extra) - Uses 500 Focus and causes great damages
image Freezing Blast (Extra) - Three waves of Chi instead of one
