- Concise description
Skill. Starts charging sequence for the N.O.X.ion Buster
- This skill is used by N.O.X..
- N.O.X. will begin using the spell N.O.X.ion Buster shortly after using this skill. While this effect is not listed, Countdown prevents N.O.X.ion Buster (but no other skills) from being interrupted until it ends. The countdown (10 seconds long) is displayed in speech bubbles above N.O.X.'s head, and the skill's effect ends when N.O.X. announces that the countdown has been completed (some time before the spell is cast), making him vulnerable to interrupts again.
