Hey, Jakk! This applies to Artifacts that increase the Champion's basic Stats. Note that it only applies to the Stats themselves, so Divine Speed for a Champion with the Lore of Steel Mastery will get an increase in Speed over the base bonus, but no increase for the Shield.

Thx a lot of your answer!

Does this work on the cruel set as well?

Hello so I have two speed sets and a divine speed set on my apothecary. Checked my speed before implementing lore of steel and was at 216. When I applied the mastery I didn’t gain any speed on my character. Is this a glitch?

Can we get answer from a developer to Tomjbru’s question? I checked the stats of my character before and after selecting the Lore of Steel Mastery and there was no changed indicated. Is this Mastery even working? Or is it bugged/broken?

Can we get a dev response to Denizen’s reply regarding Tomjbru’s question? =D 

I checked the stats of my cupidus before and after the lore of steel scroll grind; his speed went up 2, and attack up 24... lookout arena, here I come!

Edit: further research helped me define which stats were added to what and how... it’s a multiplicative boost, so an offense set with 15% attack bonus is now 17.5% attack bonus.. (15 x 1.15 = 17.5)

Crit set with a 12%  rate is now 13.8% crit rate (12 x 1.15 = 13.8)

Hope this helps anyone’s confusion!
