if BuffPresent(icy_citadel_buff) and AzeriteTraitRank(icy_citadel_trait) > 2 Spell(chains_of_ice)
never seems to work

It seem to be BuffPresent(icy_citadel_buff) is not detecting, I've changed code to all 3 available ID on wow head 272718, 272719, 272721 and none seem to work

I'm using if SpellCooldown(pillar_of_frost) < 29 and SpellCooldown(pillar_of_frost) > 25 and AzeriteTraitRank(icy_citadel_trait) > 2 Spell(chains_of_ice)
as a work around for now 272721 is the buff you get while pillar of frost is up, i can't figure out what 272718 and 272719 are doing

No idea where it came from or why wowhead not showing it, but I found a spellID that works 272723
