This mod makes the Double Vortices perk in Enderal apply to your right hand onehander, instead of to dual wielding. This is for people who enjoy onehanders over dual wielding. Unfortunately, you won't see a change in the text of the game, as I don't know how to edit the perk stones in Enderal.

This mod is complimented by the Dual Flurry to Flurry mod by ErikRedbeard. Even though that's a Skyrim mod it does seem to work with Enderal.

If you absolutely have to confirm this mod works you can download Damage Notify by Thalioden.
