My lvl 61 hunter has a smithed Daedric bow, and 3 gear items that add +100 archery. She also has all of the Archery perks. Here's how the arrows affect damage output:
+10 Steel Arrows - 339
+24 Daedric Arrows - 425 Total difference between Daedric and Steel damage output- +86
When I take off all three of the +Archery gear items, these are the same totals:
Steel - 169
Daedric - 212 For a total difference of- +43
Seems like with or without +Archery gear, the different types of arrows are adding a significantly higher amount of damage to your bow's output, than before. Anyone else noticing this?
