In many cases you do not need the full set of armor. Only stone hammers are enough to kill and Froggys toadys. Try eleven hammers, those on the list of tools, and equip the villagers with them.
Two hits with the hammer already kill. A hit to let them "slightly injured".
A few days ago I made a suggestion to add a menu to choose the behavior of the villagers. Let's wait and hope to be added.viewtopic.php?f=9&t=2793
