His abiltiy description states he does “3 hits of physical damage to single target” when in combat his numbers are always “white” instead of “red” which would be considered True Damage so which type is it?

I just tested it against Horus with Eternity set and Phycial Damage Shield up and the Assassin did 3 hits of “white” damage at 5k per hit. I then tested him against Madam with a True Damage shield and all damage was blocked. Please check the damage type description and make the appropriate changes.
