This ability's cooldown is way too long — barely usable.
Tips
register
Read aloud as English letters 'C-D'. Comes from 'cooldown' (冷却时间 lěngquè shíjiān). Conjugates Chinese-style: 在CD (on cooldown), CD好了 (cooldown is up), 缩CD (reduce cooldown).
mistakes
Don't confuse with the older 'compact disc' meaning (light-CD now obsolete in everyday speech) or 'cross-dresser' English slang. In gaming context CD is unambiguously cooldown.
