I don't make Intelligence matter for creating ideas, just ones based on logic, deduction, and knowledge. I do the same with wisdom and plans based on intuition and perception.Well, no, actually you don’t, because the game doesn’t say Intelligence has anything to do with your character’s ability to come up with good ideas or plans. What the game says Intelligence does is:
IntelligenceIntelligence measures mental acuity, accuracy of recall, and the ability to reason.
What you’re doing is running ability scores hard based on your own ideas about what the words they’re named after mean. And that’s your prerogative, but it isn’t what the rules actually describe.
So I'll let the wizard roll to "solve the logic or knowledge puzzle" if no player can figure it out. Whereas the perception puzzle might offer a Wis check for the stumped.
