I want to do an insight check, is the square lying?

i roll to seduce

How big is the square though

Somehow both 5ft on each side and 5ft across the diagonal

I feel this in my bones.

This is also every all-staff meeting my work has ever had.

So clearly here they need to roll for initiative because that is clearly a Quadrone.

Seriously though, I find the biggest problem with puzzles is the GM explaining them. If there aren't pictures people are limited by their imagination so you get crazy ideas of what exactly is going on.

I roll a 3 on my investigation check. Do I get advantage since I have Darkvision?!
