Better Aerondight is an add-on for the online game Aerondight. This addon allows you to get 3 extra rune slots, which can be used to increase the strength of your weapon. The best thing about this addon is that it can be downloaded for free.

If you already have the weapon, then you will not be able to use the extra 3 rune slots. To fix that, you need to delete your weapon and then create a new one through the console.

If you don't have the weapon, then you will need to download a different mod. 

This mod is a combination of multiple mods. It will require you to install at least one of the mods.
