I don't have it, and I'm just curious. Do you have to have the imbuments on your skill bar in order for them to apply to rain of arrows, or do you just have to have points in them?
And when you do, I don't even know what you'll do with it other than to sell it. Using a skill point on rain of arrows feels like such a downgrade for rogues.
I’m using Rain of Arrows with Word of Hakan and liking it. It clears a large area and knocks down elites so you can finish them off. Resetting cooldowns is also nice. If you time things right you can get 3 imbuemwnts in a row.
My build relies primarily on two inbuemwnts so +3 to all imbuement skills is great.
