Edge rule
(lemmy.world)
Be sure to follow the rule before you head out.
Rule: You must post before you leave.
To put it in the nerdiest way possible: just because you have high INT doesn't mean you have high WIS. And even if they did, they could have rolled a nat one on their arcana check.
Or in case you're not into baseball: smart people are sometimes idiots and brainfarts happen.
