I noticed the write-up on mound kings shows them as mindless. Does this mean they're immune to mind hunt, enslave mind, soul slay (what's to slay?), charm, hellbind heart, and anything else affecting the mind? If so, does anyone have a complete list of spells that mindless commanders are immune to? They seem like a great asset if you're going up a mind hunt happy opponent. Any drawbacks besides low commandable units?
