The Action Marker that you earn when developing the windlass allows...
From page 14...
"activate the Haspelknecht to do 3 reeling actions without pay. After use, return the action marker to the general supply. If the Haspelknecht is paid in the phase when the action marker is used, the Haspelknecht can be activated twice that phase."
From page 10...
"The Haspelknecht removes pit water from the shaft or he reels up coal from the shaft to the farm."
So the question is can the action marker be used to remove water or exclusively to raise coal?
I think the intention is to do either but the word "or" on page 10 has us wondering.
It's either waster or coal.
