So with this talk of Eternity some say no footfalls is intended to differentiate it as Eternity and not Twilight and Sunrise it makes Eternity a total let down to users who have it right? You have both weapons in one except you don’t have the full 100% Twilight effects and vise verse. Why not give Eternity footfall/footsteps with the left leg leaving Twilight’s footfalls and right foot leaving Sunrise’s footfalls?
This change would give people no confusion that it’s Eternity. There is no reason someone who spent to much time and effort into creating two legendary to have the outcome of mixing them be less memorable than the swords separately.
TL;DR
Eternity should give both Footfall effects from Twilight and Sunrise.
