Guild Wars 2

Topic says everything, how can i make my charr tail glow?
I know its citadel of Fire but is it the pants for the coat?
Is it heavy armour or lighyt armour?

Anyone knows?

I think only CoF light armor makes it glow, but not sure.

Balthazar outfit also has a fiery glowy tail. Zodiac armor has a sky glowy tail.

The CoF light pants are the only ones of that set that give charr the fiery tail. It does, luckily, work on both genders (unlike most outfits that change the tail that only display for male charr).
