So, I have seen multiple threads on this topic but no concise results/proof.
Does the ranged attack speed from Shot on the Run stack with alacrity/speed items? I did a test...
SotR (+10% attack speed bonus) + 10% ranged alacrity item (10% enhancement bonus) + speed item (6% enhancement bonus) fired 100 arrows in 70 seconds
SotR (+10% attack speed bonus) + speed item (6% enhancement bonus) fired 100 arrows in 69seconds
SotR (+10% attack speed bonus) fired 100 arrows in 71seconds
Allowing for error with me hitting stop on the stopwatch, they are all equal. So it appears SotR does NOT stack with other sources of attack speed bonuses from alacrity/speed items. They do show in different areas on the character sheet though. SotR shows up only on the Ranged Combat: Bow Attack Speed Bonus on the character sheet whereas alacrity/speed items show up only on the mouse-over Ranged Attack Speed Bonus.
Is SotR supposed to stack with other forms of alacrity or not??????? Please devs, let us know. It is a feat that has two pre-reqs and by the time you can get it you can likely find an item with 10% alacrity anyway. If it doesn't stack, LET US KNOW.
