Overflow – overloading your blast gauge : A skill that is activated by using Raging Volcano. This will overload Karok’s Cestus gauge which will cause Big Bang Attack and Blasts to multi-hit. There a critical downside to it though. You won’t be able to use Blast skills for a while after so it might be better for inexperienced players to pass this skill.
J.F. Blast – keeping enemies in check while looking for an opening : This skill decreases your gauge by 1 stack but in return gives you stamina. You can use this by pressing your kick key instead of your grab key which is the usual for Blast skills.
There can be situations where you have more Blast gauges than intended or you suddenly have the need for a lower stack Blast effect. In the past you had to use your gauge and start over but now J.F. Blast will allow you to use a lower stack Blast when needed.
Its stamina recovery also makes it useful in situation where you need the extra stamina. Once you reach a certain rank you can chain Blast right after J.F. Blast in order to get a lower stack Blast effect immediately.
Ducking – a multi-purpose evasion and distance closer : Ducking can be used as an extra evasion and dash smash after Weaving. Dempsey Roll can be used in conjunction with Ducking as well. The new evasion is faster than Weaving and can be used in multiple situations thus increasing Cestus Karok’s mobility. Ducking can be used with no stamina cost during Gigantic Strength which can further improve the speed of combat for Karok.
