All Scarab Demons have a shock damage listed that deals physical with a % chance of lightning. This is not one of their regular two melee attacks, and it's not clear how this damage is inflicted. It does seem to be enabled in the game, though.
Shock Damage:
Physical + (20%) Light:
- 5-14 + 0-2
- 19-38 + 5-11
- 51-103 + 13-26
