When you're up against these Healer Elephants, because they have so much health and they can easily be pulled back, you don't want to focus them. You want to get to an archer point where you can actually just kill all the other units, and then when there's only Healer Elephants remaining, that's when you can take the fights against them.

One of the big problems with healer elephants is that even if you make spearmen against them, it's quite difficult to get the force surround needed to get maximum value due to pathing. However, OTD spearmen, essentially two in the body of one, have an easier time getting on top and finding the sticking power to deal that massive damage.

Those gilded crossbows from OTD are one of the scariest units in the game. When they reach a critical mass, Touglak might really struggle to deal with them because of their reliance on elephants.
