(classic) spell cooldown timer

Guides UI and Macro
1

example: innervate

my main dungeon group is a priest, warrior, hunter and two druids. the druids take turns innervating the priest if there has been a mana-intensive fight, or simply to speed things along. is there a macro, script, addon to announce the remaining cooldown on innervate?

thanks in advance for any help

Think you’re looking for Weak Auras addon

Just have them add it to their cooldown tracker eg Exorsus Raid Tools
