Skyrim talk:Night Eye (power)

Easy mod fix for Werewolf nighteye[edit]
Simply change (using xEdit aka SSEedit) the record WerewolfNightEye to be an Ability (becomes innate and constant to the Werewolf race) instead of a Lesser Power. That record is found in Skyrim.esm, under Spell. You can also alter the duration while you are making such a mod.
PS : if you are using ENBseries, you must turn on the option called Apply Game Color Correction (in the section ENBeffect.fx, below Nighteye Balance). Note ENB "mods/presets" for Skyrim recommend this option be off most of the times, except when using Nighteye. Another simpler method is to temporarily turn off your ENB when you use Nighteye.
