Blacksmith UI doesn’t convey anywhere that Weapon modifiers are doubled nor Amulet modifiers are 1.5x the displayed modifier.
Ideally the UI would simply show the correct modifiers based on what item is slotted in to the crafting bench.
Additionally the UI does a poor job of clarifying the difference between the Temper Roll mentions. one of them is the maximum allowed while the other is the currently performed amount but the UI doesn’t say this anywhere.
