The worst geas (that we know of)???

I'm now chaught up with TEK and epic of gilgamesh and I was wondering what you guys think might be the worst geas a knight has right now that we know of?

And who has the "least worst" ?


currently known geases (i hope all of them, if not please let me know):

"one will not kill while looking down"

"one can only harm the other if he's standing on the ground"

"you cannot fight in the darkness/ at night"

"you can only attack those within your sight"

"you can never kill while the east is towards your back"

"you shall never harm anyone who does not speak to you"

"you can't kill anyone directly"
