Self-serving at the moment obviously -
Everyone else runs around with 10 or 11 aspect slots. Monks are stuck at 9 without a weapon / weapons.
There are probably a ton of ways to overcome this if desired, but here a couple of ideas:
Whatever gloves a monk wears counts as 2 of that aspect
Monks gain +1 to every aspect natively (monk perk?!)
A monk only item in the shops that counts as an aspect of whatever, allowing it to be purchased. One at a time only.
