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.
Lightning DMG increases by 20%. Roaring Thunder and Sonic Vortex can now be cast during the action of other Signal Orb skills, but cannot be cast consecutively. Leaving Chaotic M.I.N.D. will return Orbs based on the number of Orbs before entering Chaotic M.I.N.D. and rearrange them for 3-Ping.
Shock Echo
When taking damage, releases a shockwave that deals damage equal to 50% of own ATK, pushing enemies away and reducing enemies' Movement Speed by 35% for 5s, CD for 8s.
