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.
Basic Attack's Extra DMG Bonus increases by 10%. Physical DMG increases by 5% for 2s after each Basic Attack. Can be stacked up to 5 times. Duration resets every time it is triggered.
Incandescence
Weapon's final ATK increases by 15% at the start of battle. No duration limit.
