- How to defeat Galtran?

I've played with Galtron many times and consider him a strong hero. As for skeletons... skeletons are definitely powerful (spellcasting, high growth rate, decent attack and defense, they always get targeted by towers during sieges). Often, skeletons are the backbone of my entire army; when everyone else is defeated, liches and... skeletons remain (and there are hundreds, swarms, legions of them).

Galtron's skeletons are FREE.

What do you mean by "free"?
