So… I have a 4ga Masterwork 12 one of these. It didn’t roll imbuement skills on any of its 4th tempers, but its +3 should have increased to +4 with the basic 45% boost. However, it has not. Any clue as to why?
Because masterworking increases affix by 5% of its normal max value on a GA. The normal max value of +imbuement skills on Word of Hakan is 2.
2 x 0.45 + 3 = 3.9
Note that +skills on uniques and +skills on legendaries work differently when it comes to masterworking. For example GA +3 Defensive Skills on Barb or Sorc chest would become +4 when fully masterwork upgraded without crit proc.
