Wizards have an advancement move available at level 2:
Know-It-All
When another player’s character comes to you for advice and you tell them what you think is best, they get +1 forward when following your advice and you mark experience if they do.
Hm. I'm trying to figure out how to adjudicate this move. It seems easy enough to abuse: every other character comes to the wizard before they do anything, and hey presto, there are lots of +1 bonuses, and the wizard gains a level every time he turns around.
Clearly, that's abusive. At least, it's not something I want in my game. My players are not deliberately abusive, either, but they're going to want some kind of guideline for how often it can be used. Preferably an in-character guideline.
There's no roll for success, so no opportunity for me to impose hard choices or costs that way. The move makes no mention of requiring any relevant actual expertise from the wizard (it's even called "know-it-all"!), so as written the wizard could make up any bullshit he likes and still get the bonuses.
Of course, in the fiction, bonuses from the wizard spewing bullshit makes no sense, and I'd have to find some way to limit that. Maybe by limiting the move trigger to: "When
another player’s character comes to you for advice about something on which you have knowledge and you tell them what you think is best" -- but then, how to determine what the wizard does or doesn't have knowledge about?
I think I'm talking myself into requiring at minimum a Spout Lore roll before Know-It-All can trigger. Even so, that seems to provide incentive for a
lot of goddamn Spout Lore rolls.
Consider: "Oh wise wizard, please advise me of the best way to kill a skeleton!"
"Why certainly, my son: if you thrust up under the jaw, the skull is bound to pop right off, and then they lose all coordination." Why wouldn't that be legit? And it seems it would allow every party member to get the same advice, get the +1 for the whole battle ("when following advice"), and then bonus xp also. Why wouldn't they want to do this all the time?
I must have the wrong end of the stick here somehow. How do you guys play this move?
