A mutog is no way a vehicle, only scouting is move and back. They also aren’t good as moving wall, their morphology makes a lot less intuitive what los they block, got a soldier killed because of that.
The Mutog you buy seems always the same, for now I found it good to eat worms, there’s something special here despite their attack damage is lower than a worm HP. And this mutog get 2AP for each worm eat.
I also found it ok as cannon fooder to block a side.
It’s very hard to organize chain kill for this mutog because the damages attack is very few damage. You can still heal him a bit during a combat through making it do kills.
For now not much more. That’s why I think two slots and healing during travels should be a fine rebalance attempt.
