wow... I was afraid because I had joked about it sense I may have made it too much... andyour like "need more details" I am floored by that.That may have been me or @iserith, as that is how we both handle “recall lore” type actions. Though to clarify, I ask that players say what they hope to learn and where they may have learned it. So, your example satisfies the first (they want to learn if they have seen the symbol or anything like it before), but not where they would have learned it. So I would request the player suggest something from the character’s background where they might have come across such information. And it’s fine if it’s made up on the spot.
if i remember a relevent skill i will often just ask teh player to roll it, but if they just ask "Can I arcana that?" i get what they mean
