For a unique effect like the you describe, I would probably put that in the innate description itself. Most people don't explicitly look at the "more info" tabs (plus, those tabs wouldn't be in the League of Legends descriptions, either). Those tabs are usually for more technical, background information, like the priorities you also put in there. The extra info about the taunt (how you can still cast abilities and summoner spells) is unique enough that it should be put in the description.
