Some major changes were made in the last patch on CN. There might be bugs when China is selected. Other servers will not experience issues. My apologies for the inconvenience.
After a 3-Ping, Physical DMG and Dark DMG dealt increase by 20% for 5s. Duration resets every time it is triggered.
Tenebrion Shock
Inflicts Dark Wave effect upon dealing Dark DMG. Dark Wave: reduces the target's Dark Resistance by 8% for 8s. Repeated triggering refreshes the duration.
Dead Line Timing
Gains 2 extra random Signal Orbs when deployed, and 3 Signal Orbs of the same color every 45s (also gains Signal Orbs on standby).
Resonant Echo
The duration of effect inflicted by Tank class skill increases to 8s. Repeated triggering refreshes the duration.
