What it does
Checks whether the spell you choose is one that Blizzard's Assisted Combat can suggest for your current specialization. The spell's current override and its base spell count as the same spell.
Why you might use it
Matches when a spell is one that Blizzard's Assisted Combat can suggest for your current specialization; the spell's current override and its base spell count too. Its main use is under NOT, to highlight what Assisted Combat leaves out, for example a Warrior reminder for Avatar when that cooldown is not in Blizzard's set. Where Assisted Combat is not offered for this character or spec, or the set cannot be read, the condition is unavailable rather than false. See also Assisted Combat Suggestion.
Example
Avatar is in Blizzard's Assisted Combat rotation
Settings
What each setting in the condition editor means, from the game's own help.
Matches when this spell is one Blizzard's Assisted Combat can suggest for your current specialization. Its current override and its base spell count too. Use it to highlight what Assisted Combat leaves out, for example a cooldown that is not in the set.
The set is read again whenever your spells change, never guessed. Where the game does not offer Assisted Combat for this character or specialization, or the set cannot be read, this condition is unavailable rather than false, including under NOT.
The icon next to the spell name will automatically update to display the spell that is currently selected. You can drag a new spell from your spell book or action bars into this icon slot to replace your selected spell.
Use this exact spell rank - Unticked (the default), any rank of the spell matches. Ticked, only the rank you chose matches. (only on Classic Era, TBC Anniversary, Forever)
