Walk on Water info:

A unit that has the monster extended flag "Walks on Surface of Water" will be able to walk on water as long as they do 
not have an artifact that switches their monster tag in their inventory. Even if they drop this artifact, the unit is unable 
to walk on the surface of water. This happens even if the monster it switches with has the same extended flag on. 
Artifacts that do not swap monster tags do not have this effect. This test map shows a warrior with an artifact near it. 
Make the warrior walk on the water. Go back and grab the artifact and try to walk on the water again. This was tested 
on 361, 1.7.1, 1.7.0, and 1.6. Same results for all.
