Menen: Grab Exclamation Mark and make a sword.
If not, Try again for an attack to the head

You both get 4. It's parried.
Open chests.
Side note:
When looting a chest it goes as follows:
1- weapon
2- armor
3- gold
4- other
The lower chest is locked.
But the other one contains:
A spear!
I don't think you need it, but I guess another warrior can make use of it?
Slide against wall and backstab
That doesn't even sound possible.
